Adrien Grand commented on LUCENE-7237: -------------------------------------- For the record, there is already a test for concurrency in TestLRUQueryCache. > LRUQueryCache should rather not cache than wait on a lock > --------------------------------------------------------- > > Key: LUCENE-7237 > URL: https://issues.apache.org/jira/browse/LUCENE-7237 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Adrien Grand > Assignee: Adrien Grand > Priority: Minor > Attachments: LUCENE-7237.patch > > > This is an idea Robert just mentioned to me: currently the cache is using a > lock to keep various data-structures in sync. It is a pity that you might > have contention because of caching. So something we could do would be to not > cache when the lock is already taken. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
