Michael McCandless resolved LUCENE-1579. ---------------------------------------- Resolution: Fixed > Cloned SegmentReaders fail to share FieldCache entries > ------------------------------------------------------ > > Key: LUCENE-1579 > URL: https://issues.apache.org/jira/browse/LUCENE-1579 > Project: Lucene - Java > Issue Type: Bug > Components: Index > Affects Versions: 2.9 > Reporter: Michael McCandless > Assignee: Michael McCandless > Fix For: 2.9 > > Attachments: LUCENE-1579.patch, LUCENE-1579.patch, LUCENE-1579.patch > > > I just hit this on LUCENE-1516, which returns a cloned readOnly > readers from IndexWriter. > The problem is, when cloning, we create a new [thin] cloned > SegmentReader for each segment. FieldCache keys directly off this > object, so if you clone the reader and do a search that requires the > FieldCache (eg, sorting) then that first search is always very slow > because every single segment is reloading the FieldCache. > This is of course a complete showstopper for LUCENE-1516. > With LUCENE-831 we'll switch to a new FieldCache API; we should ensure > this bug is not present there. We should also fix the bug in the > current FieldCache API since for 2.9, users may hit this. -- 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
