    Args:
        replication_task_arn: <p>The Amazon Resource Name (ARN) of the replication task to be started.</p>
        start_replication_task_type: <p>The type of replication task to start.</p> <p> <code>start-replication</code> is the only valid action that can be used for the first time a task with the migration type of <code>full-load</code>full-load, <code>full-load-and-cdc</code> or <code>cdc</code> is run. Any other action used for the first time on a given task, such as <code>resume-processing</code> and reload-target will result in data errors.</p> <p>You can also use <a>ReloadTables</a> to reload specific tables that failed during migration instead of restarting the task.</p> <p>For a <code>full-load</code> task, the resume-processing option will reload any tables that were partially loaded or not yet loaded during the full load phase.</p> <p>For a <code>full-load-and-cdc</code> task, DMS migrates table data, and then applies data changes that occur on the source. To load all the tables again, and start capturing source changes, use <code>reload-target</code>. Otherwise use <code>resume-processing</code>, to replicate the changes from the last stop position.</p> <p>For a <code>cdc</code> only task, to start from a specific position, you must use start-replication and also specify the start position. Check the source endpoint DMS documentation for any limitations. For example, not all sources support starting from a time.</p> <note> <p> <code>resume-processing</code> is only available for previously executed tasks.</p> </note>
        cdc_start_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>
        cdc_start_position: <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>
        cdc_stop_position: <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>
