Overview

Note:

When passing ModifyReplicationTaskMessage as input to an Aws::Client method, you can use a vanilla Hash:

{
  replication_task_arn: "String", # required
  replication_task_identifier: "String",
  migration_type: "full-load", # accepts full-load, cdc, full-load-and-cdc
  table_mappings: "String",
  replication_task_settings: "String",
  cdc_start_time: Time.now,
  cdc_start_position: "String",
  cdc_stop_position: "String",
  task_data: "String",
}

Instance Attribute Details

#cdc_start_position ⇒ String

Indicates when you want a change data capture (CDC) operation to start. Use either CdcStartPosition or CdcStartTime to specify when you want a CDC operation to start. Specifying both values results in an error.

The value can be in date, checkpoint, or LSN/SCN format.

Date Example: --cdc-start-position “2018-03-08T12:12:12”

Checkpoint Example: --cdc-start-position \"checkpoint:V1#27#mysql-bin-changelog.157832:1975:-1:2002:677883278264080:mysql-bin-changelog.157832:1876#0#0#*#0#93\"

LSN Example: --cdc-start-position “mysql-bin-changelog.000024:373”

When you use this task setting with a source PostgreSQL database, a logical replication slot should already be created and associated with the source endpoint. You can verify this by setting the slotName extra connection attribute to the name of this logical replication slot. For more information, see Extra Connection Attributes When Using PostgreSQL as a Source for AWS DMS.

Returns:

  • (String) —

    Indicates when you want a change data capture (CDC) operation to start.

#cdc_start_time ⇒ Time

Indicates the start time for a change data capture (CDC) operation. Use either CdcStartTime or CdcStartPosition to specify when you want a CDC operation to start. Specifying both values results in an error.

Timestamp Example: --cdc-start-time “2018-03-08T12:12:12”

Returns:

  • (Time) —

    Indicates the start time for a change data capture (CDC) operation.

#cdc_stop_position ⇒ String

Indicates when you want a change data capture (CDC) operation to stop. The value can be either server time or commit time.

Server time example: --cdc-stop-position “server_time:2018-02-09T12:12:12”

Commit time example: --cdc-stop-position “commit_time: 2018-02-09T12:12:12 “

Returns:

  • (String) —

    Indicates when you want a change data capture (CDC) operation to stop.

#migration_type ⇒ String

The migration type. Valid values: full-load | cdc | full-load-and-cdc

Possible values:

  • full-load
  • cdc
  • full-load-and-cdc

Returns:

  • (String) —

    The migration type.

#replication_task_arn ⇒ String

The Amazon Resource Name (ARN) of the replication task.

Returns:

  • (String) —

    The Amazon Resource Name (ARN) of the replication task.

#replication_task_identifier ⇒ String

The replication task identifier.

Constraints:

  • Must contain 1-255 alphanumeric characters or hyphens.

  • First character must be a letter.

  • Cannot end with a hyphen or contain two consecutive hyphens.

Returns:

  • (String) —

    The replication task identifier.

#replication_task_settings ⇒ String

JSON file that contains settings for the task, such as task metadata settings.

Returns:

  • (String) —

    JSON file that contains settings for the task, such as task metadata settings.

#table_mappings ⇒ String

When using the AWS CLI or boto3, provide the path of the JSON file that contains the table mappings. Precede the path with file://. When working with the DMS API, provide the JSON as the parameter value, for example: --table-mappings file://mappingfile.json

Returns:

  • (String) —

    When using the AWS CLI or boto3, provide the path of the JSON file that contains the table mappings.

#task_data ⇒ String

Supplemental information that the task requires to migrate the data for certain source and target endpoints. For more information, see Specifying Supplemental Data for Task Settings in the AWS Database Migration Service User Guide.

Returns:

  • (String) —

    Supplemental information that the task requires to migrate the data for certain source and target endpoints.
