[jira] [Created] (SOLR-13668) Solr cores should release cache memory when inactive

Andrzej Bialecki  created SOLR-13668:
----------------------------------------

             Summary: Solr cores should release cache memory when inactive
                 Key: SOLR-13668
                 URL: https://issues.apache.org/jira/browse/SOLR-13668
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Andrzej Bialecki 
            Assignee: Andrzej Bialecki 
             Fix For: 8.3


(This optimization has been identified also in SOLR-13579).

Solr caches expand to fill the max limit of the cache without ever releasing the memory (unless a commit happens, in which case autowarming fills them again to some extent).

It would be nice to be able to release some of that heap if the core has not had any query requests for a configured amount of time.
