During data consumption, you can modify the consumption checkpoint based on your business requirements. After you modify the consumption checkpoint, the downstream SDK client will consume the data that is generated after the specified time.
Prerequisites
- A change tracking task is created. For more information, see Track data changes from ApsaraDB RDS for MySQL (previous).
- The change tracking task is in the Normal or Error state.
Precautions
To perform this operation, you must restart all downstream SDK consumption processes. We recommend that you perform this operation during off-peak hours to avoid service interruption.
Procedure
- Stop all downstream SDK consumption processes.
- Log on to the DTS console.
