Enables or disables image matching for a data synchronization instance.

When you use Data Transmission Service (DTS) to synchronize data, other data sources may write data to the destination instance. In this case, data may become inconsistent between the source and destination instances. To ensure data consistency, you can enable image matching.

After you call this operation, you can call the DescribeSynchronizationJobReplicatorCompare operation to verify whether image matching is enabled for the data synchronization instance.

Debugging

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.
