Subject [jira] Updated: (SOLR-1275) Add expungeDeletes to DirectUpdateHandler2
Date Wed, 19 Aug 2009 05:33:15 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1275?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jason Rutherglen updated SOLR-1275:
-----------------------------------

    Attachment: SOLR-1275.patch

* Added DirectUpdateHandlerTest.testExpungeDeletes which creates
a bunch of docs (i.e. several segments), terms known to be in
specific segments are found and deleted. Expunge deletes is
called, the segments are fewer and the segments with the deleted
terms no longer exist.

* Added expungeDeletes functionality to DirectUpdateHandler2

* The patch randomly didn't create enough of the expected
segments, this could be due to ConcurrentMergeScheduler. I
couldn't reproduce consistently.
