Data Transmission Service (DTS) allows you to add or remove change tracking objects during data consumption.

Usage notes

  • After you add an object, the change tracking task pulls data changes of the new object from the time when the modification takes effect.
  • If the change tracking client still tracks data changes of a removed object, you must filter those changes on the client.
  • To add an object for change tracking, the account configured for the change tracking task must have the required permissions on the object.

Procedure

  1. Log on to the DTS console.
  2. In the left-side navigation pane, click Change Tracking.
  3. On the Change Tracking Tasks page, select the region of your change tracking instance.
  4. For the target data subscription instance, click Modify Change Tracking Objects in the Actions column.
  5. In the Select Subscription Objects step, adjust the subscription objects. In the Data Types to Subscribe To section, select Data Updates and Structure Updates.
    • Add a subscription object

      In the Subscription Objects list, select the object to add and click 向右小箭头 to move it to the Selected Objects list.

    • Remove a subscription object

      In the Selected Objects list, select the object to remove and click 向左小箭头 to move it back to the Subscription Objects list.

  6. After you adjust the subscription objects, click save and precheck in the lower-right corner of the page.
    You are redirected to the data subscription task page. The modification is successful when the The operation is successful. message appears.
    Note The system does not perform a precheck after you modify subscription objects.

After the change tracking objects are modified, you can use a Kafka client to consume tracked data. For more information, see Consume subscribed data using a Kafka client.
