[jira] [Created] (HUDI-1348) Provide option to clean up DFS sources after each commit

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
