> How is different to just configure the StreamFileWriter with parallelism of 1? @stevenzwu I think there is twodifferent point: 1.As i said before the compaction will not block handle data in flink job because the data channel will be not block just when snapshot function completed so for handle data that compaction is in parallel in this PR. So more parallelism of StreamFileWriter will benefit fast handle data in running time, but compaction just work in the time of notifyCheckpointComplete that not affect handle data. 2. In the scene that produce little data in every checkpoint will generate small files, but if we compact files in every checkpoint will all the small files for the table as result. -- This is an automated message from the Apache Git Service.
