Show child fields gcp_my_sql_settings.after_connect_script Specifies a script to run immediately after DMS connects to the endpoint. The migration task continues running regardless if the SQL statement succeeds or fails. For this parameter, provide the code of the script itself, not the name of a file containing the script. gcp_my_sql_settings.clean_source_metadata_on_mismatch Cleans and recreates table metadata information on the replication instance when a mismatch occurs. For example, in a situation where running an alter DDL on the table could result in different information about the table cached in the replication instance. gcp_my_sql_settings.database_name Database name for the endpoint. For a MySQL source or target endpoint, don't explicitly specify the database using the DatabaseName request parameter on either the CreateEndpoint or ModifyEndpoint API call. Specifying DatabaseName when you create or modify a MySQL endpoint replicates all the task tables to this single database. For MySQL endpoints, you specify the database only when you specify the schema in the table-mapping rules of the DMS task. gcp_my_sql_settings.events_poll_interval Specifies how often to check the binary log for new changes/events when the database is idle. The default is five seconds. Example: eventsPollInterval=5; In the example, DMS checks for changes in the binary logs every five seconds. gcp_my_sql_settings.max_file_size Specifies the maximum size (in KB) of any .csv file used to transfer data to a MySQL-compatible database. Example: maxFileSize=512 gcp_my_sql_settings.parallel_load_threads Improves performance when loading data into the MySQL-compatible target database. Specifies how many threads to use to load the data into the MySQL-compatible target database. Setting a large number of threads can have an adverse effect on database performance, because a separate connection is required for each thread. The default is one. Example: parallelLoadThreads=1 gcp_my_sql_settings.password Endpoint connection password. gcp_my_sql_settings.port Endpoint TCP port. gcp_my_sql_settings.secrets_manager_access_role_arn The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret.

STRUCT( "broker" VARCHAR, "topic" VARCHAR, "message_format" VARCHAR, "include_transaction_details" BOOLEAN, "include_partition_value" BOOLEAN, "partition_include_schema_table" BOOLEAN, "include_table_alter_operations" BOOLEAN, "include_control_details" BOOLEAN, "message_max_bytes" BIGINT, "include_null_and_empty" BOOLEAN, "security_protocol" VARCHAR, "ssl_client_certificate_arn" VARCHAR, "ssl_client_key_arn" VARCHAR, "ssl_client_key_password" VARCHAR, "ssl_ca_certificate_arn" VARCHAR, "sasl_username" VARCHAR, "sasl_password" VARCHAR, "no_hex_prefix" BOOLEAN, "sasl_mechanism" VARCHAR, "ssl_endpoint_identification_algorithm" VARCHAR )
Show child fields kafka_settings.broker A comma-separated list of one or more broker locations in your Kafka cluster that host your Kafka instance. Specify each broker location in the form broker-hostname-or-ip:port . For example, "ec2-12-345-678-901.compute-1.amazonaws.com:2345". For more information and examples of specifying a list of broker locations, see Using Apache Kafka as a target for Database Migration Service in the Database Migration Service User Guide. kafka_settings.include_control_details Shows detailed control information for table definition, column definition, and table and column changes in the Kafka message output. The default is false. kafka_settings.include_null_and_empty Include NULL and empty columns for records migrated to the endpoint. The default is false. kafka_settings.include_partition_value Shows the partition value within the Kafka message output unless the partition type is schema-table-type. The default is false. kafka_settings.include_table_alter_operations Includes any data definition language (DDL) operations that change the table in the control data, such as rename-table, drop-table, add-column, drop-column, and rename-column. The default is false. kafka_settings.include_transaction_details Provides detailed transaction information from the source database. This information includes a commit timestamp, a log position, and values for transaction_id, previous transaction_id, and transaction_record_id (the record offset within a transaction). The default is false. kafka_settings.message_format The output format for the records created on the endpoint. The message format is JSON (default) or JSON_UNFORMATTED (a single line with no tab). kafka_settings.message_max_bytes The maximum size in bytes for records created on the endpoint The default is 1,000,000. kafka_settings.no_hex_prefix Set this optional parameter to true to avoid adding a '0x' prefix to raw data in hexadecimal format. For example, by default, DMS adds a '0x' prefix to the LOB column type in hexadecimal format moving from an Oracle source to a Kafka target. Use the NoHexPrefix endpoint setting to enable migration of RAW data type columns without adding the '0x' prefix. kafka_settings.partition_include_schema_table Prefixes schema and table names to partition values, when the partition type is primary-key-type. Doing this increases data distribution among Kafka partitions. For example, suppose that a SysBench schema has thousands of tables and each table has only limited range for a primary key. In this case, the same primary key is sent from thousands of tables to the same partition, which causes throttling. The default is false. kafka_settings.sasl_mechanism For SASL/SSL authentication, DMS supports the SCRAM-SHA-512 mechanism by default. DMS versions 3.5.0 and later also support the PLAIN mechanism. To use the PLAIN mechanism, set this parameter to PLAIN. kafka_settings.sasl_password The secure password you created when you first set up your MSK cluster to validate a client identity and make an encrypted connection between server and client using SASL-SSL authentication. kafka_settings.sasl_username The secure user name you created when you first set up your MSK cluster to validate a client identity and make an encrypted connection between server and client using SASL-SSL authentication. kafka_settings.security_protocol Set secure connection to a Kafka target endpoint using Transport Layer Security (TLS). Options include ssl-encryption, ssl-authentication, and sasl-ssl. sasl-ssl requires SaslUsername and SaslPassword. kafka_settings.ssl_ca_certificate_arn The Amazon Resource Name (ARN) for the private certificate authority (CA) cert that DMS uses to securely connect to your Kafka target endpoint. kafka_settings.ssl_client_certificate_arn The Amazon Resource Name (ARN) of the client certificate used to securely connect to a Kafka target endpoint. kafka_settings.ssl_client_key_arn The Amazon Resource Name (ARN) for the client private key used to securely connect to a Kafka target endpoint. kafka_settings.ssl_client_key_password The password for the client private key used to securely connect to a Kafka target endpoint. kafka_settings.ssl_endpoint_identification_algorithm Sets hostname verification for the certificate. This setting is supported in DMS version 3.5.1 and later. kafka_settings.topic The topic to which you migrate the data. If you don't specify a topic, DMS specifies "kafka-default-topic" as the migration topic.

The default is false. kinesis_settings.include_partition_value Shows the partition value within the Kinesis message output, unless the partition type is schema-table-type. The default is false. kinesis_settings.include_table_alter_operations Includes any data definition language (DDL) operations that change the table in the control data, such as rename-table, drop-table, add-column, drop-column, and rename-column. The default is false. kinesis_settings.include_transaction_details Provides detailed transaction information from the source database. This information includes a commit timestamp, a log position, and values for transaction_id, previous transaction_id, and transaction_record_id (the record offset within a transaction). The default is false. kinesis_settings.message_format The output format for the records created on the endpoint. The message format is JSON (default) or JSON_UNFORMATTED (a single line with no tab). kinesis_settings.no_hex_prefix Set this optional parameter to true to avoid adding a '0x' prefix to raw data in hexadecimal format. For example, by default, DMS adds a '0x' prefix to the LOB column type in hexadecimal format moving from an Oracle source to an Amazon Kinesis target. Use the NoHexPrefix endpoint setting to enable migration of RAW data type columns without adding the '0x' prefix. kinesis_settings.partition_include_schema_table Prefixes schema and table names to partition values, when the partition type is primary-key-type. Doing this increases data distribution among Kinesis shards. For example, suppose that a SysBench schema has thousands of tables and each table has only limited range for a primary key. In this case, the same primary key is sent from thousands of tables to the same shard, which causes throttling. The default is false. kinesis_settings.service_access_role_arn The Amazon Resource Name (ARN) for the IAM role that DMS uses to write to the Kinesis data stream. The role must allow the iam:PassRole action. kinesis_settings.stream_arn The Amazon Resource Name (ARN) for the Amazon Kinesis Data Streams endpoint.
kms_key_id An KMS key identifier that is used to encrypt the connection parameters for the endpoint.

STRUCT( "port" BIGINT, "bcp_packet_size" BIGINT, "database_name" VARCHAR, "control_tables_file_group" VARCHAR, "password" VARCHAR, "query_single_always_on_node" BOOLEAN, "read_backup_only" BOOLEAN, "safeguard_policy" VARCHAR, "server_name" VARCHAR, "username" VARCHAR, "use_bcp_full_load" BOOLEAN, "use_third_party_backup_device" BOOLEAN, "secrets_manager_access_role_arn" VARCHAR, "secrets_manager_secret_id" VARCHAR, "trim_space_in_char" BOOLEAN, "tlog_access_mode" VARCHAR, "force_lob_lookup" BOOLEAN )
Show child fields microsoft_sql_server_settings.bcp_packet_size The maximum size of the packets (in bytes) used to transfer data using BCP. microsoft_sql_server_settings.control_tables_file_group Specifies a file group for the DMS internal tables. When the replication task starts, all the internal DMS control tables (awsdms_ apply_exception, awsdms_apply, awsdms_changes) are created for the specified file group. microsoft_sql_server_settings.database_name Database name for the endpoint. microsoft_sql_server_settings.force_lob_lookup Forces LOB lookup on inline LOB. microsoft_sql_server_settings.password Endpoint connection password. microsoft_sql_server_settings.port Endpoint TCP port. microsoft_sql_server_settings.query_single_always_on_node Cleans and recreates table metadata information on the replication instance when a mismatch occurs. An example is a situation where running an alter DDL statement on a table might result in different information about the table cached in the replication instance. microsoft_sql_server_settings.read_backup_only When this attribute is set to Y, DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication. microsoft_sql_server_settings.safeguard_policy Use this attribute to minimize the need to access the backup log and enable DMS to prevent truncation using one of the following two methods. Start transactions in the database: This is the default method. When this method is used, DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method. Exclusively use sp_repldone within a single task: When this method is used, DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one DMS task can access the database at any given time. Therefore, if you need to run parallel DMS tasks against the same database, use the default method. microsoft_sql_server_settings.secrets_manager_access_role_arn The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret. The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the SQL Server endpoint. You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId. Or you can specify clear-text values for UserName, Password, ServerName, and Port. You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide. microsoft_sql_server_settings.secrets_manager_secret_id The full ARN, partial ARN, or friendly name of the SecretsManagerSecret that contains the SQL Server endpoint connection details. microsoft_sql_server_settings.server_name Fully qualified domain name of the endpoint. For an Amazon RDS SQL Server instance, this is the output of DescribeDBInstances, in the Endpoint.Address field. microsoft_sql_server_settings.tlog_access_mode Indicates the mode used to fetch CDC data. microsoft_sql_server_settings.trim_space_in_char Use the TrimSpaceInChar source endpoint setting to right-trim data on CHAR and NCHAR data types during migration. Setting TrimSpaceInChar does not left-trim data. The default value is true. microsoft_sql_server_settings.use_bcp_full_load Use this to attribute to transfer data for full-load operations using BCP. When the target table contains an identity column that does not exist in the source table, you must disable the use BCP for loading table option. microsoft_sql_server_settings.use_third_party_backup_device When this attribute is set to Y, DMS processes third-party transaction log backups if they are created in native format. microsoft_sql_server_settings.username Endpoint connection user name.

For MongoDB Atlas, provide the server name for any of the servers in the replication set. mongo_db_settings.use_update_look_up If true, DMS retrieves the entire document from the MongoDB source during migration. This may cause a migration failure if the server response exceeds bandwidth limits. To fetch only updates and deletes during migration, set this parameter to false. mongo_db_settings.username The user name you use to access the MongoDB source endpoint.
my_sql_settings The settings for the MySQL source and target endpoint. For more information, see the MySQLSettings structure.	STRUCT( "after_connect_script" VARCHAR, "clean_source_metadata_on_mismatch" BOOLEAN, "database_name" VARCHAR, "events_poll_interval" BIGINT, "target_db_type" VARCHAR, "max_file_size" BIGINT, "parallel_load_threads" BIGINT, "password" VARCHAR, "port" BIGINT, "server_name" VARCHAR, "server_timezone" VARCHAR, "username" VARCHAR, "secrets_manager_access_role_arn" VARCHAR, "secrets_manager_secret_id" VARCHAR, "execute_timeout" BIGINT )
Show child fields my_sql_settings.after_connect_script Specifies a script to run immediately after DMS connects to the endpoint. The migration task continues running regardless if the SQL statement succeeds or fails. For this parameter, provide the code of the script itself, not the name of a file containing the script. my_sql_settings.clean_source_metadata_on_mismatch Cleans and recreates table metadata information on the replication instance when a mismatch occurs. For example, in a situation where running an alter DDL on the table could result in different information about the table cached in the replication instance. my_sql_settings.database_name Database name for the endpoint. For a MySQL source or target endpoint, don't explicitly specify the database using the DatabaseName request parameter on either the CreateEndpoint or ModifyEndpoint API call. Specifying DatabaseName when you create or modify a MySQL endpoint replicates all the task tables to this single database. For MySQL endpoints, you specify the database only when you specify the schema in the table-mapping rules of the DMS task. my_sql_settings.events_poll_interval Specifies how often to check the binary log for new changes/events when the database is idle. The default is five seconds. Example: eventsPollInterval=5; In the example, DMS checks for changes in the binary logs every five seconds. my_sql_settings.execute_timeout Sets the client statement timeout (in seconds) for a MySQL source endpoint. my_sql_settings.max_file_size Specifies the maximum size (in KB) of any .csv file used to transfer data to a MySQL-compatible database. Example: maxFileSize=512 my_sql_settings.parallel_load_threads Improves performance when loading data into the MySQL-compatible target database. Specifies how many threads to use to load the data into the MySQL-compatible target database. Setting a large number of threads can have an adverse effect on database performance, because a separate connection is required for each thread. The default is one. Example: parallelLoadThreads=1 my_sql_settings.password Endpoint connection password. my_sql_settings.port Endpoint TCP port. my_sql_settings.secrets_manager_access_role_arn The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret. The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the MySQL endpoint. You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId. Or you can specify clear-text values for UserName, Password, ServerName, and Port. You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide. my_sql_settings.secrets_manager_secret_id The full ARN, partial ARN, or friendly name of the SecretsManagerSecret that contains the MySQL endpoint connection details. my_sql_settings.server_name The host name of the endpoint database. For an Amazon RDS MySQL instance, this is the output of DescribeDBInstances, in the Endpoint.Address field. For an Aurora MySQL instance, this is the output of DescribeDBClusters, in the Endpoint field. my_sql_settings.server_timezone Specifies the time zone for the source MySQL database. Example: serverTimezone=US/Pacific; Note: Do not enclose time zones in single quotes. my_sql_settings.target_db_type Specifies where to migrate source tables on the target, either to a single database or multiple databases.

Show child fields neptune_settings.error_retry_duration The number of milliseconds for DMS to wait to retry a bulk-load of migrated graph data to the Neptune target database before raising an error. The default is 250. neptune_settings.iam_auth_enabled If you want Identity and Access Management (IAM) authorization enabled for this endpoint, set this parameter to true. Then attach the appropriate IAM policy document to your service role specified by ServiceAccessRoleArn. The default is false. neptune_settings.max_file_size The maximum size in kilobytes of migrated graph data stored in a .csv file before DMS bulk-loads the data to the Neptune target database. The default is 1,048,576 KB. If the bulk load is successful, DMS clears the bucket, ready to store the next batch of migrated graph data. neptune_settings.max_retry_count The number of times for DMS to retry a bulk load of migrated graph data to the Neptune target database before raising an error. The default is 5. neptune_settings.s3_bucket_folder A folder path where you want DMS to store migrated graph data in the S3 bucket specified by S3BucketName neptune_settings.s3_bucket_name The name of the Amazon S3 bucket where DMS can temporarily store migrated graph data in .csv files before bulk-loading it to the Neptune target database. DMS maps the SQL source data to graph data before storing it in these .csv files. neptune_settings.service_access_role_arn The Amazon Resource Name (ARN) of the service role that you created for the Neptune target endpoint. The role must allow the iam:PassRole action. For more information, see Creating an IAM Service Role for Accessing Amazon Neptune as a Target in the Database Migration Service User Guide.
oracle_settings The settings for the Oracle source and target endpoint. For more information, see the OracleSettings structure.	STRUCT( "add_supplemental_logging" BOOLEAN, "archived_log_dest_id" BIGINT, "additional_archived_log_dest_id" BIGINT, "extra_archived_log_dest_ids" BIGINT[], "allow_select_nested_tables" BOOLEAN, "parallel_asm_read_threads" BIGINT, "read_ahead_blocks" BIGINT, "access_alternate_directly" BOOLEAN, "use_alternate_folder_for_online" BOOLEAN, "oracle_path_prefix" VARCHAR, "use_path_prefix" VARCHAR, "replace_path_prefix" BOOLEAN, "enable_homogenous_tablespace" BOOLEAN, "direct_path_no_log" BOOLEAN, "archived_logs_only" BOOLEAN, "asm_password" VARCHAR, "asm_server" VARCHAR, "asm_user" VARCHAR, "char_length_semantics" VARCHAR, "database_name" VARCHAR, "direct_path_parallel_load" BOOLEAN, "fail_tasks_on_lob_truncation" BOOLEAN, "number_datatype_scale" BIGINT, "password" VARCHAR, "port" BIGINT, "read_table_space_name" BOOLEAN, "retry_interval" BIGINT, "security_db_encryption" VARCHAR, "security_db_encryption_name" VARCHAR, "server_name" VARCHAR, "spatial_data_option_to_geo_json_function_name" VARCHAR, "standby_delay_time" BIGINT, "username" VARCHAR, "use_b_file" BOOLEAN, "use_direct_path_full_load" BOOLEAN, "use_logminer_reader" BOOLEAN, "secrets_manager_access_role_arn" VARCHAR, "secrets_manager_secret_id" VARCHAR, "secrets_manager_oracle_asm_access_role_arn" VARCHAR, "secrets_manager_oracle_asm_secret_id" VARCHAR, "trim_space_in_char" BOOLEAN, "convert_timestamp_with_zone_to_utc" BOOLEAN, "open_transaction_window" BIGINT )
Show child fields oracle_settings.access_alternate_directly Set this attribute to false in order to use the Binary Reader to capture change data for an Amazon RDS for Oracle as the source. This tells the DMS instance to not access redo logs through any specified path prefix replacement using direct file access. oracle_settings.add_supplemental_logging Set this attribute to set up table-level supplemental logging for the Oracle database. This attribute enables PRIMARY KEY supplemental logging on all tables selected for a migration task. If you use this option, you still need to enable database-level supplemental logging. oracle_settings.additional_archived_log_dest_id Set this attribute with ArchivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover. Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless necessary. For additional information about RESETLOGS, see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide. oracle_settings.allow_select_nested_tables Set this attribute to true to enable replication of Oracle tables containing columns that are nested tables or defined types. oracle_settings.archived_log_dest_id Specifies the ID of the destination for the archived redo logs. This value should be the same as a number in the dest_id column of the v$archived_log view. If you work with an additional redo log destination, use the AdditionalArchivedLogDestId option to specify the additional destination ID. Doing this improves performance by ensuring that the correct logs are accessed from the outset. oracle_settings.archived_logs_only When this field is set to Y, DMS only accesses the archived redo logs. If the archived redo logs are stored on Automatic Storage Management (ASM) only, the DMS user account needs to be granted ASM privileges. oracle_settings.asm_password For an Oracle source endpoint, your Oracle Automatic Storage Management (ASM) password. You can set this value from the asm_user_password value. You set this value as part of the comma-separated value that you set to the Password request parameter when you create the endpoint to access transaction logs using Binary Reader. For more information, see Configuration for change data capture (CDC) on an Oracle source database. oracle_settings.asm_server For an Oracle source endpoint, your ASM server address. You can set this value from the asm_server value. You set asm_server as part of the extra connection attribute string to access an Oracle server with Binary Reader that uses ASM. For more information, see Configuration for change data capture (CDC) on an Oracle source database. oracle_settings.asm_user For an Oracle source endpoint, your ASM user name. You can set this value from the asm_user value. You set asm_user as part of the extra connection attribute string to access an Oracle server with Binary Reader that uses ASM. For more information, see Configuration for change data capture (CDC) on an Oracle source database. oracle_settings.char_length_semantics Specifies whether the length of a character column is in bytes or in characters. To indicate that the character column length is in characters, set this attribute to CHAR. Otherwise, the character column length is in bytes. Example: charLengthSemantics=CHAR; oracle_settings.convert_timestamp_with_zone_to_utc When true, converts timestamps with the timezone datatype to their UTC value. oracle_settings.database_name Database name for the endpoint. oracle_settings.direct_path_no_log When set to true, this attribute helps to increase the commit rate on the Oracle target database by writing directly to tables and not writing a trail to database logs. oracle_settings.direct_path_parallel_load When set to true, this attribute specifies a parallel load when useDirectPathFullLoad is set to Y. This attribute also only applies when you use the DMS parallel load feature. Note that the target table cannot have any constraints or indexes. oracle_settings.enable_homogenous_tablespace Set this attribute to enable homogenous tablespace replication and create existing tables or indexes under the same tablespace on the target. oracle_settings.extra_archived_log_dest_ids[] oracle_settings.fail_tasks_on_lob_truncation When set to true, this attribute causes a task to fail if the actual size of an LOB column is greater than the specified LobMaxSize. If a task is set to limited LOB mode and this option is set to true, the task fails instead of truncating the LOB data. oracle_settings.number_datatype_scale Specifies the number scale. You can select a scale up to 38, or you can select FLOAT. By default, the NUMBER data type is converted to precision 38, scale 10. Example: numberDataTypeScale=12 oracle_settings.open_transaction_window The timeframe in minutes to check for open transactions for a CDC-only task. You can specify an integer value between 0 (the default) and 240 (the maximum). This parameter is only valid in DMS version 3.5.0 and later. DMS supports a window of up to 9.5 hours including the value for OpenTransactionWindow. oracle_settings.oracle_path_prefix Set this string attribute to the required value in order to use the Binary Reader to capture change data for an Amazon RDS for Oracle as the source. This value specifies the default Oracle root used to access the redo logs. oracle_settings.parallel_asm_read_threads Set this attribute to change the number of threads that DMS configures to perform a change data capture (CDC) load using Oracle Automatic Storage Management (ASM). You can specify an integer value between 2 (the default) and 8 (the maximum). Use this attribute together with the readAheadBlocks attribute. oracle_settings.password Endpoint connection password. oracle_settings.port Endpoint TCP port. oracle_settings.read_ahead_blocks Set this attribute to change the number of read-ahead blocks that DMS configures to perform a change data capture (CDC) load using Oracle Automatic Storage Management (ASM). You can specify an integer value between 1000 (the default) and 200,000 (the maximum). oracle_settings.read_table_space_name When set to true, this attribute supports tablespace replication. oracle_settings.replace_path_prefix Set this attribute to true in order to use the Binary Reader to capture change data for an Amazon RDS for Oracle as the source. This setting tells DMS instance to replace the default Oracle root with the specified usePathPrefix setting to access the redo logs. oracle_settings.retry_interval Specifies the number of seconds that the system waits before resending a query. Example: retryInterval=6; oracle_settings.secrets_manager_access_role_arn The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret. The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the Oracle endpoint. You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId. Or you can specify clear-text values for UserName, Password, ServerName, and Port. You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide. oracle_settings.secrets_manager_oracle_asm_access_role_arn Required only if your Oracle endpoint uses Automatic Storage Management (ASM). The full ARN of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the SecretsManagerOracleAsmSecret. This SecretsManagerOracleAsmSecret has the secret value that allows access to the Oracle ASM of the endpoint. You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerOracleAsmSecretId. Or you can specify clear-text values for AsmUser, AsmPassword, and AsmServerName. You can't specify both. For more information on creating this SecretsManagerOracleAsmSecret and the SecretsManagerOracleAsmAccessRoleArn and SecretsManagerOracleAsmSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide. oracle_settings.secrets_manager_oracle_asm_secret_id Required only if your Oracle endpoint uses Automatic Storage Management (ASM). The full ARN, partial ARN, or friendly name of the SecretsManagerOracleAsmSecret that contains the Oracle ASM connection details for the Oracle endpoint. oracle_settings.secrets_manager_secret_id The full ARN, partial ARN, or friendly name of the SecretsManagerSecret that contains the Oracle endpoint connection details. oracle_settings.security_db_encryption For an Oracle source endpoint, the transparent data encryption (TDE) password required by AWM DMS to access Oracle redo logs encrypted by TDE using Binary Reader. It is also the TDE_Password part of the comma-separated value you set to the Password request parameter when you create the endpoint. The SecurityDbEncryptian setting is related to this SecurityDbEncryptionName setting. For more information, see Supported encryption methods for using Oracle as a source for DMS in the Database Migration Service User Guide. oracle_settings.security_db_encryption_name For an Oracle source endpoint, the name of a key used for the transparent data encryption (TDE) of the columns and tablespaces in an Oracle source database that is encrypted using TDE. The key value is the value of the SecurityDbEncryption setting. For more information on setting the key name value of SecurityDbEncryptionName, see the information and example for setting the securityDbEncryptionName extra connection attribute in Supported encryption methods for using Oracle as a source for DMS in the Database Migration Service User Guide. oracle_settings.server_name Fully qualified domain name of the endpoint. For an Amazon RDS Oracle instance, this is the output of DescribeDBInstances, in the Endpoint.Address field. oracle_settings.spatial_data_option_to_geo_json_function_name Use this attribute to convert SDO_GEOMETRY to GEOJSON format. By default, DMS calls the SDO2GEOJSON custom function if present and accessible. Or you can create your own custom function that mimics the operation of SDOGEOJSON and set SpatialDataOptionToGeoJsonFunctionName to call it instead. oracle_settings.standby_delay_time Use this attribute to specify a time in minutes for the delay in standby sync. If the source is an Oracle Active Data Guard standby database, use this attribute to specify the time lag between primary and standby databases. In DMS, you can create an Oracle CDC task that uses an Active Data Guard standby instance as a source for replicating ongoing changes. Doing this eliminates the need to connect to an active database that might be in production. oracle_settings.trim_space_in_char Use the TrimSpaceInChar source endpoint setting to trim data on CHAR and NCHAR data types during migration. The default value is true. oracle_settings.use_alternate_folder_for_online Set this attribute to true in order to use the Binary Reader to capture change data for an Amazon RDS for Oracle as the source. This tells the DMS instance to use any specified prefix replacement to access all online redo logs. oracle_settings.use_b_file Set this attribute to Y to capture change data using the Binary Reader utility. Set UseLogminerReader to N to set this attribute to Y. To use Binary Reader with Amazon RDS for Oracle as the source, you set additional attributes. For more information about using this setting with Oracle Automatic Storage Management (ASM), see Using Oracle LogMiner or DMS Binary Reader for CDC. oracle_settings.use_direct_path_full_load Set this attribute to Y to have DMS use a direct path full load. Specify this value to use the direct path protocol in the Oracle Call Interface (OCI). By using this OCI protocol, you can bulk-load Oracle target tables during a full load. oracle_settings.use_logminer_reader Set this attribute to Y to capture change data using the Oracle LogMiner utility (the default). Set this attribute to N if you want to access the redo logs as a binary file. When you set UseLogminerReader to N, also set UseBfile to Y. For more information on this setting and using Oracle ASM, see Using Oracle LogMiner or DMS Binary Reader for CDC in the DMS User Guide. oracle_settings.use_path_prefix Set this string attribute to the required value in order to use the Binary Reader to capture change data for an Amazon RDS for Oracle as the source. This value specifies the path prefix used to replace the default Oracle root to access the redo logs. oracle_settings.username Endpoint connection user name.

postgre_sql_settings The settings for the PostgreSQL source and target endpoint. For more information, see the PostgreSQLSettings structure.	STRUCT( "after_connect_script" VARCHAR, "capture_ddls" BOOLEAN, "max_file_size" BIGINT, "database_name" VARCHAR, "ddl_artifacts_schema" VARCHAR, "execute_timeout" BIGINT, "fail_tasks_on_lob_truncation" BOOLEAN, "heartbeat_enable" BOOLEAN, "heartbeat_schema" VARCHAR, "heartbeat_frequency" BIGINT, "password" VARCHAR, "port" BIGINT, "server_name" VARCHAR, "username" VARCHAR, "slot_name" VARCHAR, "plugin_name" VARCHAR, "secrets_manager_access_role_arn" VARCHAR, "secrets_manager_secret_id" VARCHAR, "trim_space_in_char" BOOLEAN, "map_boolean_as_boolean" BOOLEAN, "map_jsonb_as_clob" BOOLEAN, "map_long_varchar_as" VARCHAR, "database_mode" VARCHAR, "babelfish_database_name" VARCHAR )
Show child fields postgre_sql_settings.after_connect_script For use with change data capture (CDC) only, this attribute has DMS bypass foreign keys and user triggers to reduce the time it takes to bulk load data. Example: afterConnectScript=SET session_replication_role='replica' postgre_sql_settings.babelfish_database_name The Babelfish for Aurora PostgreSQL database name for the endpoint. postgre_sql_settings.capture_ddls To capture DDL events, DMS creates various artifacts in the PostgreSQL database when the task starts. You can later remove these artifacts. If this value is set to N, you don't have to create tables or triggers on the source database. postgre_sql_settings.database_mode Specifies the default behavior of the replication's handling of PostgreSQL- compatible endpoints that require some additional configuration, such as Babelfish endpoints. postgre_sql_settings.database_name Database name for the endpoint. postgre_sql_settings.ddl_artifacts_schema The schema in which the operational DDL database artifacts are created. Example: ddlArtifactsSchema=xyzddlschema; postgre_sql_settings.execute_timeout Sets the client statement timeout for the PostgreSQL instance, in seconds. The default value is 60 seconds. Example: executeTimeout=100; postgre_sql_settings.fail_tasks_on_lob_truncation When set to true, this value causes a task to fail if the actual size of a LOB column is greater than the specified LobMaxSize. If task is set to Limited LOB mode and this option is set to true, the task fails instead of truncating the LOB data. postgre_sql_settings.heartbeat_enable The write-ahead log (WAL) heartbeat feature mimics a dummy transaction. By doing this, it prevents idle logical replication slots from holding onto old WAL logs, which can result in storage full situations on the source. This heartbeat keeps restart_lsn moving and prevents storage full scenarios. postgre_sql_settings.heartbeat_frequency Sets the WAL heartbeat frequency (in minutes). postgre_sql_settings.heartbeat_schema Sets the schema in which the heartbeat artifacts are created. postgre_sql_settings.map_boolean_as_boolean When true, lets PostgreSQL migrate the boolean type as boolean. By default, PostgreSQL migrates booleans as varchar(5). You must set this setting on both the source and target endpoints for it to take effect. postgre_sql_settings.map_jsonb_as_clob When true, DMS migrates JSONB values as CLOB. postgre_sql_settings.map_long_varchar_as When true, DMS migrates LONG values as VARCHAR. postgre_sql_settings.max_file_size Specifies the maximum size (in KB) of any .csv file used to transfer data to PostgreSQL. Example: maxFileSize=512 postgre_sql_settings.password Endpoint connection password. postgre_sql_settings.plugin_name Specifies the plugin to use to create a replication slot. postgre_sql_settings.port Endpoint TCP port. The default is 5432. postgre_sql_settings.secrets_manager_access_role_arn The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret. The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the PostgreSQL endpoint. You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId. Or you can specify clear-text values for UserName, Password, ServerName, and Port. You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide. postgre_sql_settings.secrets_manager_secret_id The full ARN, partial ARN, or friendly name of the SecretsManagerSecret that contains the PostgreSQL endpoint connection details. postgre_sql_settings.server_name The host name of the endpoint database. For an Amazon RDS PostgreSQL instance, this is the output of DescribeDBInstances, in the Endpoint.Address field. For an Aurora PostgreSQL instance, this is the output of DescribeDBClusters, in the Endpoint field. postgre_sql_settings.slot_name Sets the name of a previously created logical replication slot for a change data capture (CDC) load of the PostgreSQL source instance. When used with the CdcStartPosition request parameter for the DMS API , this attribute also makes it possible to use native CDC start points. DMS verifies that the specified logical replication slot exists before starting the CDC load task. It also verifies that the task was created with a valid setting of CdcStartPosition. If the specified slot doesn't exist or the task doesn't have a valid CdcStartPosition setting, DMS raises an error. For more information about setting the CdcStartPosition request parameter, see Determining a CDC native start point in the Database Migration Service User Guide. For more information about using CdcStartPosition, see CreateReplicationTask, StartReplicationTask, and ModifyReplicationTask. postgre_sql_settings.trim_space_in_char Use the TrimSpaceInChar source endpoint setting to trim data on CHAR and NCHAR data types during migration. The default value is true. postgre_sql_settings.username Endpoint connection user name.
redis_settings The settings for the Redis target endpoint. For more information, see the RedisSettings structure.	STRUCT( "server_name" VARCHAR, "port" BIGINT, "ssl_security_protocol" VARCHAR, "auth_type" VARCHAR, "auth_user_name" VARCHAR, "auth_password" VARCHAR, "ssl_ca_certificate_arn" VARCHAR )
Show child fields redis_settings.auth_password The password provided with the auth-role and auth-token options of the AuthType setting for a Redis target endpoint. redis_settings.auth_type The type of authentication to perform when connecting to a Redis target. Options include none, auth-token, and auth-role. The auth-token option requires an AuthPassword value to be provided. The auth-role option requires AuthUserName and AuthPassword values to be provided. redis_settings.auth_user_name The user name provided with the auth-role option of the AuthType setting for a Redis target endpoint. redis_settings.port Transmission Control Protocol (TCP) port for the endpoint. redis_settings.server_name Fully qualified domain name of the endpoint. redis_settings.ssl_ca_certificate_arn The Amazon Resource Name (ARN) for the certificate authority (CA) that DMS uses to connect to your Redis target endpoint. redis_settings.ssl_security_protocol The connection to a Redis target endpoint using Transport Layer Security (TLS). Valid values include plaintext and ssl-encryption. The default is ssl-encryption. The ssl-encryption option makes an encrypted connection. Optionally, you can identify an Amazon Resource Name (ARN) for an SSL certificate authority (CA) using the SslCaCertificateArn setting. If an ARN isn't given for a CA, DMS uses the Amazon root CA. The plaintext option doesn't provide Transport Layer Security (TLS) encryption for traffic between endpoint and database.
redshift_settings Settings for the Amazon Redshift endpoint.	STRUCT( "accept_any_date" BOOLEAN, "after_connect_script" VARCHAR, "bucket_folder" VARCHAR, "bucket_name" VARCHAR, "case_sensitive_names" BOOLEAN, "comp_update" BOOLEAN, "connection_timeout" BIGINT, "database_name" VARCHAR, "date_format" VARCHAR, "empty_as_null" BOOLEAN, "encryption_mode" VARCHAR, "explicit_ids" BOOLEAN, "file_transfer_upload_streams" BIGINT, "load_timeout" BIGINT, "max_file_size" BIGINT, "password" VARCHAR, "port" BIGINT, "remove_quotes" BOOLEAN, "replace_invalid_chars" VARCHAR, "replace_chars" VARCHAR, "server_name" VARCHAR, "service_access_role_arn" VARCHAR, "server_side_encryption_kms_key_id" VARCHAR, "time_format" VARCHAR, "trim_blanks" BOOLEAN, "truncate_columns" BOOLEAN, "username" VARCHAR, "write_buffer_size" BIGINT, "secrets_manager_access_role_arn" VARCHAR, "secrets_manager_secret_id" VARCHAR, "map_boolean_as_boolean" BOOLEAN )
Show child fields redshift_settings.accept_any_date A value that indicates to allow any date format, including invalid formats such as 00/00/00 00:00:00, to be loaded without generating an error. You can choose true or false (the default). This parameter applies only to TIMESTAMP and DATE columns. Always use ACCEPTANYDATE with the DATEFORMAT parameter. If the date format for the data doesn't match the DATEFORMAT specification, Amazon Redshift inserts a NULL value into that field. redshift_settings.after_connect_script Code to run after connecting. This parameter should contain the code itself, not the name of a file containing the code. redshift_settings.bucket_folder An S3 folder where the comma-separated-value (.csv) files are stored before being uploaded to the target Redshift cluster. For full load mode, DMS converts source records into .csv files and loads them to the BucketFolder/TableID path. DMS uses the Redshift COPY command to upload the .csv files to the target table. The files are deleted once the COPY operation has finished. For more information, see COPY in the Amazon Redshift Database Developer Guide. For change-data-capture (CDC) mode, DMS creates a NetChanges table, and loads the .csv files to this BucketFolder/NetChangesTableID path. redshift_settings.bucket_name The name of the intermediate S3 bucket used to store .csv files before uploading data to Redshift. redshift_settings.case_sensitive_names If Amazon Redshift is configured to support case sensitive schema names, set CaseSensitiveNames to true. The default is false. redshift_settings.comp_update If you set CompUpdate to true Amazon Redshift applies automatic compression if the table is empty. This applies even if the table columns already have encodings other than RAW. If you set CompUpdate to false, automatic compression is disabled and existing column encodings aren't changed. The default is true. redshift_settings.connection_timeout A value that sets the amount of time to wait (in milliseconds) before timing out, beginning from when you initially establish a connection. redshift_settings.database_name The name of the Amazon Redshift data warehouse (service) that you are working with. redshift_settings.date_format The date format that you are using. Valid values are auto (case-sensitive), your date format string enclosed in quotes, or NULL. If this parameter is left unset (NULL), it defaults to a format of 'YYYY-MM-DD'. Using auto recognizes most strings, even some that aren't supported when you use a date format string. If your date and time values use formats different from each other, set this to auto. redshift_settings.empty_as_null A value that specifies whether DMS should migrate empty CHAR and VARCHAR fields as NULL. A value of true sets empty CHAR and VARCHAR fields to null. The default is false. redshift_settings.encryption_mode The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS. For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3. But you can’t change the existing value from SSE_S3 to SSE_KMS. To use SSE_S3, create an Identity and Access Management (IAM) role with a policy that allows "arn:aws:s3:::*" to use the following actions: "s3:PutObject", "s3:ListBucket" redshift_settings.explicit_ids This setting is only valid for a full-load migration task. Set ExplicitIds to true to have tables with IDENTITY columns override their auto-generated values with explicit values loaded from the source data files used to populate the tables. The default is false. redshift_settings.file_transfer_upload_streams The number of threads used to upload a single file. This parameter accepts a value from 1 through 64. It defaults to 10. The number of parallel streams used to upload a single .csv file to an S3 bucket using S3 Multipart Upload. For more information, see Multipart upload overview. FileTransferUploadStreams accepts a value from 1 through 64. It defaults to 10. redshift_settings.load_timeout The amount of time to wait (in milliseconds) before timing out of operations performed by DMS on a Redshift cluster, such as Redshift COPY, INSERT, DELETE, and UPDATE. redshift_settings.map_boolean_as_boolean When true, lets Redshift migrate the boolean type as boolean. By default, Redshift migrates booleans as varchar(1). You must set this setting on both the source and target endpoints for it to take effect. redshift_settings.max_file_size The maximum size (in KB) of any .csv file used to load data on an S3 bucket and transfer data to Amazon Redshift. It defaults to 1048576KB (1 GB). redshift_settings.password The password for the user named in the username property. redshift_settings.port The port number for Amazon Redshift. The default value is 5439. redshift_settings.remove_quotes A value that specifies to remove surrounding quotation marks from strings in the incoming data. All characters within the quotation marks, including delimiters, are retained. Choose true to remove quotation marks. The default is false. redshift_settings.replace_chars A value that specifies to replaces the invalid characters specified in ReplaceInvalidChars, substituting the specified characters instead. The default is "?". redshift_settings.replace_invalid_chars A list of characters that you want to replace. Use with ReplaceChars. redshift_settings.secrets_manager_access_role_arn The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret. The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the Amazon Redshift endpoint. You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId. Or you can specify clear-text values for UserName, Password, ServerName, and Port. You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide. redshift_settings.secrets_manager_secret_id The full ARN, partial ARN, or friendly name of the SecretsManagerSecret that contains the Amazon Redshift endpoint connection details. redshift_settings.server_name The name of the Amazon Redshift cluster you are using. redshift_settings.server_side_encryption_kms_key_id The KMS key ID. If you are using SSE_KMS for the EncryptionMode, provide this key ID. The key that you use needs an attached policy that enables IAM user permissions and allows use of the key. redshift_settings.service_access_role_arn The Amazon Resource Name (ARN) of the IAM role that has access to the Amazon Redshift service. The role must allow the iam:PassRole action. redshift_settings.time_format The time format that you want to use. Valid values are auto (case-sensitive), 'timeformat_string', 'epochsecs', or 'epochmillisecs'. It defaults to 10. Using auto recognizes most strings, even some that aren't supported when you use a time format string. If your date and time values use formats different from each other, set this parameter to auto. redshift_settings.trim_blanks A value that specifies to remove the trailing white space characters from a VARCHAR string. This parameter applies only to columns with a VARCHAR data type. Choose true to remove unneeded white space. The default is false. redshift_settings.truncate_columns A value that specifies to truncate data in columns to the appropriate number of characters, so that the data fits in the column. This parameter applies only to columns with a VARCHAR or CHAR data type, and rows with a size of 4 MB or less. Choose true to truncate data. The default is false. redshift_settings.username An Amazon Redshift user name for a registered user. redshift_settings.write_buffer_size The size (in KB) of the in-memory file write buffer used when generating .csv files on the local disk at the DMS replication instance. The default value is 1000 (buffer size is 1000KB).
s3_settings The settings for the S3 target endpoint. For more information, see the S3Settings structure.

Show child fields s3_settings.add_column_name An optional parameter that, when set to true or y, you can use to add column name information to the .csv output file. The default value is false. Valid values are true, false, y, and n. s3_settings.add_trailing_padding_character Use the S3 target endpoint setting AddTrailingPaddingCharacter to add padding on string data. The default value is false. s3_settings.bucket_folder An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path bucketFolder/schema_name/table_name/. If this parameter isn't specified, then the path used is schema_name/table_name/. s3_settings.bucket_name The name of the S3 bucket. s3_settings.canned_acl_for_objects A value that enables DMS to specify a predefined (canned) access control list for objects created in an Amazon S3 bucket as .csv or .parquet files. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 Developer Guide. The default value is NONE. Valid values include NONE, PRIVATE, PUBLIC_READ, PUBLIC_READ_WRITE, AUTHENTICATED_READ, AWS_EXEC_READ, BUCKET_OWNER_READ, and BUCKET_OWNER_FULL_CONTROL. s3_settings.cdc_inserts_and_updates A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false, but when CdcInsertsAndUpdates is set to true or y, only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file. DMS supports the use of the .parquet files in versions 3.4.7 and later. How these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true, the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false, CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide.. DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later. CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both. s3_settings.cdc_inserts_only A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target. If CdcInsertsOnly is set to true or y, only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad. If IncludeOpForFullLoad is set to true, the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false, every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide.. DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later. CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both. s3_settings.cdc_max_batch_interval Maximum length of the interval, defined in seconds, after which to output a file to Amazon S3. When CdcMaxBatchInterval and CdcMinFileSize are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template. The default value is 60 seconds. s3_settings.cdc_min_file_size Minimum file size, defined in kilobytes, to reach for a file output to Amazon S3. When CdcMinFileSize and CdcMaxBatchInterval are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template. The default value is 32 MB. s3_settings.cdc_path Specifies the folder path of CDC files. For an S3 source, this setting is required if a task captures change data; otherwise, it's optional. If CdcPath is set, DMS reads CDC files from this path and replicates the data changes to the target endpoint. For an S3 target if you set PreserveTransactions to true, DMS verifies that you have set this parameter to a folder path on your S3 target where DMS can save the transaction order for the CDC load. DMS creates this CDC folder path in either your S3 target working directory or the S3 target location specified by BucketFolder and BucketName . For example, if you specify CdcPath as MyChangedData, and you specify BucketName as MyTargetBucket but do not specify BucketFolder, DMS creates the CDC folder path following: MyTargetBucket/MyChangedData. If you specify the same CdcPath, and you specify BucketName as MyTargetBucket and BucketFolder as MyTargetData, DMS creates the CDC folder path following: MyTargetBucket/MyTargetData/MyChangedData. For more information on CDC including transaction order on an S3 target, see Capturing data changes (CDC) including transaction order on the S3 target. This setting is supported in DMS versions 3.4.2 and later. s3_settings.compression_type An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats. s3_settings.csv_delimiter The delimiter used to separate columns in the .csv file for both source and target. The default is a comma. s3_settings.csv_no_sup_value This setting only applies if your Amazon S3 output files during a change data capture (CDC) load are written in .csv format. If UseCsvNoSupValue is set to true, specify a string value that you want DMS to use for all columns not included in the supplemental log. If you do not specify a string value, DMS uses the null value for these columns regardless of the UseCsvNoSupValue setting. This setting is supported in DMS versions 3.4.1 and later. s3_settings.csv_null_value An optional parameter that specifies how DMS treats null values. While handling the null value, you can use this parameter to pass a user-defined string as null when writing to the target. For example, when target columns are nullable, you can use this option to differentiate between the empty string value and the null value. So, if you set this parameter value to the empty string ("" or ''), DMS treats the empty string as the null value instead of NULL. The default value is NULL. Valid values include any valid string. s3_settings.csv_row_delimiter The delimiter used to separate rows in the .csv file for both source and target. The default is a carriage return (\n). s3_settings.data_format The format of the data that you want to use for output. You can choose one of the following: csv : This is a row-based file format with comma-separated values (.csv). parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response. s3_settings.data_page_size The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only. s3_settings.date_partition_delimiter Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH. Use this parameter when DatePartitionedEnabled is set to true. s3_settings.date_partition_enabled When set to true, this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false. For more information about date-based folder partitioning, see Using date-based folder partitioning. s3_settings.date_partition_sequence Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD. Use this parameter when DatePartitionedEnabled is set to true. s3_settings.date_partition_timezone When creating an S3 target endpoint, set DatePartitionTimezone to convert the current UTC time into a specified time zone. The conversion occurs when a date partition folder is created and a CDC filename is generated. The time zone format is Area/Location. Use this parameter when DatePartitionedEnabled is set to true, as shown in the following example. s3-settings='{"DatePartitionEnabled": true, "DatePartitionSequence": "YYYYMMDDHH", "DatePartitionDelimiter": "SLASH", "DatePartitionTimezone":"Asia/Seoul", "BucketName": "dms-nattarat-test"}' s3_settings.dict_page_size_limit The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN. This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only. s3_settings.enable_statistics A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL, DISTINCT, MAX, and MIN values. This parameter defaults to true. This value is used for .parquet file format only. s3_settings.encoding_type The type of encoding you are using: RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default. PLAIN doesn't use encoding at all. Values are stored as they are. PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk. s3_settings.encryption_mode The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS. For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3. But you can’t change the existing value from SSE_S3 to SSE_KMS. To use SSE_S3, you need an Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions: s3:CreateBucket s3:ListBucket s3:DeleteBucket s3:GetBucketLocation s3:GetObject s3:PutObject s3:DeleteObject s3:GetObjectVersion s3:GetBucketPolicy s3:PutBucketPolicy s3:DeleteBucketPolicy s3_settings.expected_bucket_owner To specify a bucket owner and prevent sniping, you can use the ExpectedBucketOwner endpoint setting. Example: --s3-settings='{"ExpectedBucketOwner": "AWS_Account_ID"}' When you make a request to test a connection or perform a migration, S3 checks the account ID of the bucket owner against the specified parameter. s3_settings.external_table_definition Specifies how tables are defined in the S3 source files only. s3_settings.glue_catalog_generation When true, allows Glue to catalog your S3 bucket. Creating an Glue catalog lets you use Athena to query your data. s3_settings.ignore_header_rows When this value is set to 1, DMS ignores the first row header in a .csv file. A value of 1 turns on the feature; a value of 0 turns off the feature. The default is 0. s3_settings.include_op_for_full_load A value that enables a full load to write INSERT operations to the comma-separated value (.csv) or .parquet output files only to indicate how the rows were added to the source database. DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later. DMS supports the use of the .parquet files with the IncludeOpForFullLoad parameter in versions 3.4.7 and later. For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y, the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load. This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide.. s3_settings.max_file_size A value that specifies the maximum size (in KB) of any .csv file to be created while migrating to an S3 target during full load. The default value is 1,048,576 KB (1 GB). Valid values include 1 to 1,048,576. s3_settings.parquet_timestamp_in_millisecond A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format. DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later. When ParquetTimestampInMillisecond is set to true or y, DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision. Currently, Amazon Athena and Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or Glue. DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision. Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter. s3_settings.parquet_version The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0. s3_settings.preserve_transactions If set to true, DMS saves the transaction order for a change data capture (CDC) load on the Amazon S3 target specified by CdcPath . For more information, see Capturing data changes (CDC) including transaction order on the S3 target. This setting is supported in DMS versions 3.4.2 and later. s3_settings.rfc4180 For an S3 source, when this value is set to true or y, each leading double quotation mark has to be followed by an ending double quotation mark. This formatting complies with RFC 4180. When this value is set to false or n, string literals are copied to the target as is. In this case, a delimiter (row or column) signals the end of the field. Thus, you can't use a delimiter as part of the string, because it signals the end of the value. For an S3 target, an optional parameter used to set behavior to comply with RFC 4180 for data migrated to Amazon S3 using .csv file format only. When this value is set to true or y using Amazon S3 as a target, if the data has quotation marks or newline characters in it, DMS encloses the entire column with an additional pair of double quotation marks ("). Every quotation mark within the data is repeated twice. The default value is true. Valid values include true, false, y, and n. s3_settings.row_group_length The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only. If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024). s3_settings.server_side_encryption_kms_key_id If you are using SSE_KMS for the EncryptionMode, provide the KMS key ID. The key that you use needs an attached policy that enables Identity and Access Management (IAM) user permissions and allows use of the key. Here is a CLI example: aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=value,BucketFolder=value,BucketName=value,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=value s3_settings.service_access_role_arn The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action. It is a required parameter that enables DMS to write and read objects from an S3 bucket. s3_settings.timestamp_column_name A value that when nonblank causes DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target. DMS supports the TimestampColumnName parameter in versions 3.1.4 and later. DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value. For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS. For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database. The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS. By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database. When the AddColumnName parameter is set to true, DMS also includes a name for the timestamp column that you set with TimestampColumnName. s3_settings.use_csv_no_sup_value This setting applies if the S3 output files during a change data capture (CDC) load are written in .csv format. If set to true for columns not included in the supplemental log, DMS uses the value specified by CsvNoSupValue . If not set or set to false, DMS uses the null value for these columns. This setting is supported in DMS versions 3.4.1 and later. s3_settings.use_task_start_time_for_full_load_timestamp When set to true, this parameter uses the task start time as the timestamp column value instead of the time data is written to target. For full load, when useTaskStartTimeForFullLoadTimestamp is set to true, each row of the timestamp column contains the task start time. For CDC loads, each row of the timestamp column contains the transaction commit time. When useTaskStartTimeForFullLoadTimestamp is set to false, the full load timestamp in the timestamp column increments with the time data arrives at the target.
server_name The name of the server at the endpoint.	VARCHAR
service_access_role_arn The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action.	VARCHAR
ssl_mode The SSL mode used to connect to the endpoint. The default value is none.	VARCHAR

Show child fields sybase_settings.database_name Database name for the endpoint. sybase_settings.password Endpoint connection password. sybase_settings.port Endpoint TCP port. The default is 5000. sybase_settings.secrets_manager_access_role_arn The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret. The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the SAP ASE endpoint. You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId. Or you can specify clear-text values for UserName, Password, ServerName, and Port. You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide. sybase_settings.secrets_manager_secret_id The full ARN, partial ARN, or friendly name of the SecretsManagerSecret that contains the SAP SAE endpoint connection details. sybase_settings.server_name Fully qualified domain name of the endpoint. sybase_settings.username Endpoint connection user name.
timestream_settings The settings for the Amazon Timestream target endpoint. For more information, see the TimestreamSettings structure.	STRUCT( "database_name" VARCHAR, "memory_duration" BIGINT, "magnetic_duration" BIGINT, "cdc_inserts_and_updates" BOOLEAN, "enable_magnetic_store_writes" BOOLEAN )
Show child fields timestream_settings.cdc_inserts_and_updates Set this attribute to true to specify that DMS only applies inserts and updates, and not deletes. Amazon Timestream does not allow deleting records, so if this value is false, DMS nulls out the corresponding record in the Timestream database rather than deleting it. timestream_settings.database_name Database name for the endpoint. timestream_settings.enable_magnetic_store_writes Set this attribute to true to enable memory store writes. When this value is false, DMS does not write records that are older in days than the value specified in MagneticDuration, because Amazon Timestream does not allow memory writes by default. For more information, see Storage in the Amazon Timestream Developer Guide. timestream_settings.magnetic_duration Set this attribute to specify the default magnetic duration applied to the Amazon Timestream tables in days. This is the number of days that records remain in magnetic store before being discarded. For more information, see Storage in the Amazon Timestream Developer Guide. timestream_settings.memory_duration Set this attribute to specify the length of time to store all of the tables in memory that are migrated into Amazon Timestream from the source database. Time is measured in units of hours. When Timestream data comes in, it first resides in memory for the specified duration, which allows quick access to it.
username The user name used to connect to the endpoint.	VARCHAR

Note

Tables may require input columns to have values specified before the table can return it’s rows. The values for input parameters are set in the where clause of the query typically using = or IN.
