Subject [jira] [Created] (SOLR-3486) The memory size of Solr caches should be configurable
Date Thu, 24 May 2012 16:01:29 GMT
Adrien Grand created SOLR-3486:
----------------------------------

             Summary: The memory size of Solr caches should be configurable
                 Key: SOLR-3486
                 URL: https://issues.apache.org/jira/browse/SOLR-3486
             Project: Solr
          Issue Type: Improvement
          Components: search
            Reporter: Adrien Grand
            Priority: Minor


It is currently possible to configure the sizes of Solr caches based on the number of entries
of the cache. The problem is that the memory size of cached values may vary a lot over time
(depending on IndexReader.maxDoc and the queries that are run) although the JVM heap size
does not.

Having a configurable max size in bytes would also help optimize cache utilization, making
it possible to store more values provided that they have a small memory footprint.
