             Summary: Allow sharing of large in memory data structures across cores
                 Key: SOLR-8349
                 URL: https://issues.apache.org/jira/browse/SOLR-8349
             Project: Solr
          Issue Type: Improvement
          Components: Server
    Affects Versions: 5.3
            Reporter: Gus Heck


In some cases search components or analysis classes may utilize a large dictionary or other in-memory structure. When multiple cores are loaded with identical configurations utilizing this large in memory structure, each core holds it's own copy in memory. This has been noted in the past and a specific case reported in SOLR-3443. This patch provides a generalized capability, and if accepted, this capability will then be used to fix SOLR-3443.
