modify-replication-task

Description

Modifies the specified replication task.

You can't modify the task endpoints. The task must be stopped before you can modify it.

For more information about AWS DMS tasks, see Working with Migration Tasks in the AWS Database Migration Service User Guide .

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  modify-replication-task
--replication-task-arn <value>
[--replication-task-identifier <value>]
[--migration-type <value>]
[--table-mappings <value>]
[--replication-task-settings <value>]
[--cdc-start-time <value>]
[--cdc-start-position <value>]
[--cdc-stop-position <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--replication-task-arn (string)

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

--replication-task-identifier (string)

The replication task identifier.

Constraints:

  • Must contain from 1 to 255 alphanumeric characters or hyphens.
  • First character must be a letter.
  • Cannot end with a hyphen or contain two consecutive hyphens.

--migration-type (string)

The migration type.

Valid values: full-load | cdc | full-load-and-cdc

Possible values:

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

--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

--replication-task-settings (string)

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

--cdc-start-time (timestamp)

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”

--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”

--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:3018-02-09T12:12:12”

Commit time example: --cdc-stop-position “commit_time: 3018-02-09T12:12:12 “

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.
