If task is set to Limited LOB mode and this option is set to true, the task fails instead of truncating the LOB data.

Returns:

  SENSITIVE = [:password]
  include Aws::Structure
end

#heartbeat_enable ⇒ Boolean

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.

Returns:

• (Boolean)

  SENSITIVE = [:password]
  include Aws::Structure
end

#map_boolean_as_boolean ⇒ 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.

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.

#slot_name ⇒ String

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.

Returns:

• (String)
