[jira] [Created] (LUCENE-7237) LRUQueryCache

Adrien Grand created LUCENE-7237:
------------------------------------

             Summary: LRUQueryCache 
                 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


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.
