Pauses a data synchronization task.

  • When you call this operation, the data synchronization task must be in the Synchronizing state.
  • We recommend that you do not pause a data synchronization task for more than 6 hours. Otherwise, the task cannot be started again.
  • If the billing method is pay-as-you-go, DTS charges a fee even when the task is paused. This is because DTS only stops writing data to the destination database. DTS continues to pull the logs of the source database so that the task can resume quickly after it is restarted. Therefore, data synchronization consumes resources such as the bandwidth of the source database.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer automatically generates the sample code of the operation for different SDKs.
