Modify subscription object

Last Updated: Jun 22, 2017

DTS supports dynamic modification of the subscription objects during the subscription consumption process.

If you add a new subscription object, the subscription instance pulls the change data of the newly added object from the current timestamp after the modification takes effect. If you remove a subscription object, SDK no longer subscribes to the removed object data once the modification takes effect.

This section introduces how to change subscription objects on the console.

Procedure

  1. Log on to the Alibaba Cloud DTS Console.

  2. On the Data subscription page, click Change Subscription Object in More for the data subscription to be modified.

  3. On the subscription object selection page, add or remove subscription objects as needed, or modify the data type if necessary.

    修改订阅对象

  4. When the modification is complete, a pre-check is performed on the task. After the pre-check is successful, click to subscribe. The subscription instance will be re-initialized.

    When the initialization is completed, the modification takes effect. You can view the modified subscription data or use the SDK to subscribe to change data.
