[jira] [Created] (SOLR-13558) Allow dynamic resizing of SolrCache-s

             Summary: Allow dynamic resizing of SolrCache-s
                 Key: SOLR-13558
                 URL: https://issues.apache.org/jira/browse/SOLR-13558
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Andrzej Bialecki 
            Assignee: Andrzej Bialecki 


Currently SolrCache limits are configured statically and can't be reconfigured without cache re-initialization (core reload), which is costly. In some situations it would help to be able to dynamically re-size the cache based on the resource contention (such as the total heap size used for caching across all cores in a node).

Each cache implementation already knows how to evict its entries when it runs into configured limits - what is missing is to expose this mechanism using a uniform API.
