Jason Gerlowski commented on SOLR-14728: ---------------------------------------- Hey [~jbernste] I'm going to close this out as a duplicate of SOLR-15049. I wouldn't've created that ticket if I'd realized this one existed, but the newer ticket already has an associated PR, so this should be the one we close. > Add self join optimization to the TopLevelJoinQuery > --------------------------------------------------- > > Key: SOLR-14728 > URL: https://issues.apache.org/jira/browse/SOLR-14728 > Project: Solr > Issue Type: New Feature > Reporter: Joel Bernstein > Priority: Major > > A simple optimization can be put in place to massively improve join > performance when the TopLevelJoinQuery is performing a self join (same core) > and the *to* and *from* fields are the same field. In this scenario the top > level doc values ordinals can be used directly as a filter avoiding the most > expensive part of the join which is the bytes ref reconciliation between the > *to* and *from* fields. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
