[jira] [Commented] (HUDI-945) Cleanup spillable map files eagerly
as part of close
[ https://issues.apache.org/jira/browse/HUDI-945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17143445#comment-17143445 ]
renyi.bao commented on HUDI-945:
--------------------------------
hi [~vbalaji]，I noticed that the current implementation is that only one file exists in the ExternalSpillableMap, (DiskBasedMap) ，maybe we can add a method 'release()' in ExternalSpillableMap and call it explicitly?

> URL: https://issues.apache.org/jira/browse/HUDI-945
> Project: Apache Hudi
> Issue Type: Bug
> Components: Writer Core
> Reporter: Balaji Varadarajan
> Priority: Major
> Fix For: 0.6.0
>
>
> 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
