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 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
