Verifying the data consistency between sink and source is a public Issue.. I hope to discuss with you in another PR, such as how to preset data and assert verification. I think this is required for all E2E use cases. Currently, only DM has preset SQL for all fields, and other E2E has only a few fields -- This is an automated message from the Apache Git Service.
