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

     [ https://issues.apache.org/jira/browse/HUDI-1348?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vu Ho updated HUDI-1348:
------------------------
    Description: 
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 clean up the source 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
