> As discussed offline, the new implementation has been modified.
>  * Don't perform a scan during the planning phase. Instead, we put a flag along with part spec to indicate it is ordinary manual trigger compaction.
>  * Introduce a new {{PrecommittingSinkWriter}} impl to perform dedicated compaction tasks. This writer is responsible for scanning and selecting partition and bucket according to the current sub-task id, and then creating a per-bucket compact writer to submit compaction. Since there's no data shuffled between source and sink, so all the compaction is performed when {{SinkWriterOperator#endInput}} is invoked.
