Jason Rutherglen commented on LUCENE-2047: ------------------------------------------ Without syncing on the writer, we run into the SR's files being deleted out from under it while it's being obtained for deletion (I think). > IndexWriter should immediately resolve deleted docs to docID in > near-real-time mode > ----------------------------------------------------------------------------------- > > Key: LUCENE-2047 > URL: https://issues.apache.org/jira/browse/LUCENE-2047 > Project: Lucene - Java > Issue Type: Improvement > Components: Index > Reporter: Michael McCandless > Assignee: Michael McCandless > Priority: Minor > Fix For: 3.1 > > Attachments: LUCENE-2047.patch, LUCENE-2047.patch > > > Spinoff from LUCENE-1526. > When deleteDocuments(Term) is called, we currently always buffer the > Term and only later, when it's time to flush deletes, resolve to > docIDs. This is necessary because we don't in general hold > SegmentReaders open. > But, when IndexWriter is in NRT mode, we pool the readers, and so > deleting in the foreground is possible. > It's also beneficial, in that in can reduce the turnaround time when > reopening a new NRT reader by taking this resolution off the reopen > path. And if multiple threads are used to do the deletion, then we > gain concurrency, vs reopen which is not concurrent when flushing the > deletes. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
