Headers

X-Amz-Target'AmazonDMSv20160101.CreateReplicationTask' required

Request body

ReplicationTaskIdentifierstring required
<p>An identifier for the replication task.</p> <p>Constraints:</p> <ul> <li> <p>Must contain 1-255 alphanumeric characters or hyphens.</p> </li> <li> <p>First character must be a letter.</p> </li> <li> <p>Cannot end with a hyphen or contain two consecutive hyphens.</p> </li> </ul>
SourceEndpointArnstring required

An Amazon Resource Name (ARN) that uniquely identifies the source endpoint.

TargetEndpointArnstring required

An Amazon Resource Name (ARN) that uniquely identifies the target endpoint.

ReplicationInstanceArnstring required

The Amazon Resource Name (ARN) of a replication instance.

MigrationType'full-load' | 'cdc' | 'full-load-and-cdc' required

The migration type. Valid values: <code>full-load</code> | <code>cdc</code> | <code>full-load-and-cdc</code>

TableMappingsstring required

The table mappings for the task, in JSON format. For more information, see <a href="https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Tasks.CustomizingTasks.TableMapping.html">Using Table Mapping to Specify Task Settings</a> in the <i>Database Migration Service User Guide.</i>

ReplicationTaskSettingsstring

Overall settings for the task, in JSON format. For more information, see <a href="https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Tasks.CustomizingTasks.TaskSettings.html">Specifying Task Settings for Database Migration Service Tasks</a> in the <i>Database Migration Service User Guide.</i>

CdcStartTimestring date-time
<p>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.</p> <p>Timestamp Example: --cdc-start-time “2018-03-08T12:12:12”</p>
CdcStartPositionstring
<p>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.</p> <p> The value can be in date, checkpoint, or LSN/SCN format.</p> <p>Date Example: --cdc-start-position “2018-03-08T12:12:12”</p> <p>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"</p> <p>LSN Example: --cdc-start-position “mysql-bin-changelog.000024:373”</p> <note> <p>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 <code>slotName</code> extra connection attribute to the name of this logical replication slot. For more information, see <a href="https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.PostgreSQL.html#CHAP_Source.PostgreSQL.ConnectionAttrib">Extra Connection Attributes When Using PostgreSQL as a Source for DMS</a>.</p> </note>
CdcStopPositionstring
<p>Indicates when you want a change data capture (CDC) operation to stop. The value can be either server time or commit time.</p> <p>Server time example: --cdc-stop-position “server_time:2018-02-09T12:12:12”</p> <p>Commit time example: --cdc-stop-position “commit_time: 2018-02-09T12:12:12“</p>
TaskDatastring

Supplemental information that the task requires to migrate the data for certain source and target endpoints. For more information, see <a href="https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Tasks.TaskData.html">Specifying Supplemental Data for Task Settings</a> in the <i>Database Migration Service User Guide.</i>

ResourceIdentifierstring

A friendly name for the resource identifier at the end of the <code>EndpointArn</code> response parameter that is returned in the created <code>Endpoint</code> object. The value for this parameter can have up to 31 characters. It can contain only ASCII letters, digits, and hyphen ('-'). Also, it can't end with a hyphen or contain two consecutive hyphens, and can only begin with a letter, such as <code>Example-App-ARN1</code>. For example, this value might result in the <code>EndpointArn</code> value <code>arn:aws:dms:eu-west-1:012345678901:rep:Example-App-ARN1</code>. If you don't specify a <code>ResourceIdentifier</code> value, DMS generates a default identifier value for the end of <code>EndpointArn</code>.

Response

Success
