With DTS, you can modify the subscription object during a 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 when the modification takes effect. If you remove a subscription object, SDK no longer subscribes to the removed object data when the modification takes effect.
Procedure
Follow these steps to change the subscription object.
Log on to the Alibaba Cloud DTS console.
On the Data subscription page, click More > Change subscription object under the target data subscription channel.
On the subscription object selection page, you can add or remove subscription objects, or modify the data type.
When the modification is complete, a pre-check is performed on the task.
After the pre-check passes, click To subscribe to re-initialize the subscription instance.
When the initialization is complete, the modification takes effect. You can view the modified subscription data or use the SDK to subscribe to change data.
