Vu Ho created HUDI-1348:
---------------------------
Summary: Provide option to clean up DFS sources after each commit
Key: HUDI-1348
URL: https://issues.apache.org/jira/browse/HUDI-1348
Project: Apache Hudi
Issue Type: Improvement
Components: DeltaStreamer, Utilities
Reporter: Vu Ho
Since DeltaStreamer makes heavily use of file listing, if the source contains a
lot of tiny files, this could quickly become a bottle neck. We need a way to
delete/archive files once processed by DeltaStreamer.
It seems like the best way to reliably remove/archive the processed files is
after DeltaSync commit the checkpoint successfully. We could add a new public
method to Source e.g. `postCommit()` and invoke it after each successful commit
