[jira] Created: (SOLR-1609) Create a cache implementation that limits itself to a given RAM size

Hudson (Jira)
Create a cache implementation that limits itself to a given RAM size
--------------------------------------------------------------------

                 Key: SOLR-1609
                 URL: https://issues.apache.org/jira/browse/SOLR-1609
             Project: Solr
          Issue Type: New Feature
    Affects Versions: 1.4
            Reporter: Jason Rutherglen
            Priority: Minor
             Fix For: 1.5


This is a spinoff from the unrelated SOLR-1308. We can limit the
cache sizes by estimated RAM usage. I think in some cases this
is a better approach when compared with using soft references as
this will effectively limit the cache RAM used. Soft references
will utilize the max heap before divesting itself of excessive
cached items, which in some cases may not be the desired
behavior.
