[jira] [Commented] (HUDI-945) Cleanup spillable map files eagerly as part of close

["Balaji Varadarajan (Jira)" <ji...@apache.org>]

Balaji Varadarajan commented on HUDI-945:
-----------------------------------------

[~baobaoyeye]: Sorry for the delay. I missed this message. The idea is correct but we need to implement such cleanup using "clear()" method as it is part of Map interface and call it explicitly.

> Currently, files used by external spillable map or deleted on exits. For spark-streaming/deltastreamer continuous-mode cases which runs several iterations, it is better to eagerly delete files on closing the handles using it. 
> We need to eagerly delete the files on following cases:
>  # MergeHandle
>  # HoodieMergedLogRecordScanner
>  # SpillableMapBasedFileSystemView
