Task settings for change processing DDL handling

The following settings determine how Amazon DMS handles data definition language (DDL) changes for target tables during change data capture (CDC). For information about how to use a task configuration file to set task settings, see Task settings example.

Task settings to handle change processing DDL include the following:

  • HandleSourceTableDropped – Set this option to true to drop the target table when the source table is dropped.

  • HandleSourceTableTruncated – Set this option to true to truncate the target table when the source table is truncated.

  • HandleSourceTableAltered – Set this option to true to alter the target table when the source table is altered.

Following is an example of how task settings that handle change processing DDL appear in a task setting JSON file:


                "ChangeProcessingDdlHandlingPolicy": {
                   "HandleSourceTableDropped": true,
                   "HandleSourceTableTruncated": true,
                   "HandleSourceTableAltered": true
                },
Note
