Full Load Task Settings

Full load settings include the following:

  • To indicate how to handle loading the target at full-load startup, specify one of the following values for the TargetTablePrepMode option:

    • DO_NOTHING – Data and metadata of the existing target table are not affected.

    • DROP_AND_CREATE – The existing table is dropped and a new table is created in its place.

    • TRUNCATE_BEFORE_LOAD – Data is truncated without affecting the table metadata.

  • To delay primary key or unique index creation until after full load completes, set the CreatePkAfterFullLoad option. 
When this option is selected, you cannot resume incomplete full load tasks.

  • For full load and CDC-enabled tasks, you can set the following Stop task after full load completes options:

    • StopTaskCachedChangesApplied – Set this option to true to stop a task after a full load completes and cached changes are applied.

    • StopTaskCachedChangesNotApplied – Set this option to true to stop a task before cached changes are applied.

  • MaxFullLoadSubTasks – Set this option to indicate the maximum number of tables to load in parallel. The default is 8; the maximum value is 50.

  • To set the number of seconds that AWS DMS waits for transactions to close before beginning a full-load operation, if transactions are open when the task starts, set the TransactionConsistencyTimeout option. The default value is 600 (10 minutes). AWS DMS begins the full load after the timeout value is reached, even if there are open transactions.

  • To indicate the maximum number of events that can be transferred together, set the CommitRate option.
