I found some pull request about this feature https://github.com/apache/incubator-seatunnel/pull/3850. Only write data when checkpoint is a way to ensure exactly-once. But I'm afraid this will cause OOM exception, because this may let sink save more data in memory. Some times the source read is very fast(such as File Source Connector), If the sink save data in memory, OOM is almost inevitable. -- This is an automated message from the Apache Git Service.
