### Search before asking - [X] I had searched in the [feature](https://github.com/apache/incubator-seatunnel/issues?q=is%3Aissue+label%3A%22Feature%22) and found no similar feature requirement. ### Description We need support data consistency test in connector v2 e2e. I have some idea about it and welcome everyone to discuss. #### Fake Source If we want to test the data consistency of a sink connector, We can use the `Fake Source` connector. The Fake Source Connector support define row numbers and Primary key fields in the feature. Defile Primary key fields is useful to test exactly-once sink which implement exactly-once by Idempotent write data. If we can simulate task failure and then restore task, We can complete the data consistency test. #### How to simulate task failure and restore task. I think we can use `Fake Source` connector to simulate task failure too. We can add some active triggering failure function in Fake Source. To ensure Fake Source can support read playback, the Fake Source need support snapshot too. #### How to check data We can check the rows that wrote in sink. ### Usage Scenario _No response_ ### Related issues _No response_ ### Are you willing to submit a PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
