[jira] [Commented] (LUCENE-5330) IndexWriter doesn't process all events on getReader / close / rollback

["Michael McCandless (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-5330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13814805#comment-13814805 ] 

Michael McCandless commented on LUCENE-5330:
--------------------------------------------

Hmm, besides deleting files too late, are there any other problems caused here?

E.g., if an app that only flushes via getReader, would this mean a merge never kicks off (merge starvation)?

> IndexWriter misses to apply all pending events in getReader() as well as close() / rollback(). This can lead to files that never get deleted or only very very late. If you are using RAM Directories for instance this quickly fills up a huge amount of memory. It might not be super critical in production and it also doesn't cause any data loss or index corruption.
