You can modify the consumption timestamp at any time during a consumption process.
When the consumption timestamp is changed, the change data pulled by SDKs starts from the new consumption timestamp. The new consumption timestamp must be within the data range of the subscription instance. DTS can only change a consumption timestamp in the console, and does not support a specified consumption timestamp in the SDK.
Procedure
Follow these steps to change the consumption timestamp.
Stop the SDK consumption process. Before modifying the consumption timestamp, verify that all SDKs connected to the subscription instance are stopped.
You can check the consumer source of the subscription instance for verification. If the consumer sources is empty, then all downstream SDKs of the subscription instance are stopped.
Log on to the Alibaba Cloud DTS console and go to the Data subscription page.
Hover your mouse over the Consumption time of the target subscription channel, and then click
.On the Change consumption time page, select the consumption time as needed.
Note: The consumption time must be within the time range of the subscription channel.
After the consumption time is modified, restart the SDK consumption process. SDK then subscribes to the change data from the new consumption time.
