             Summary: Cache config or index schema objects by configset and 
share them across cores
                 Key: SOLR-7282
                 URL: https://issues.apache.org/jira/browse/SOLR-7282
             Project: Solr
          Issue Type: Sub-task
          Components: SolrCloud
            Reporter: Shalin Shekhar Mangar
            Assignee: Shalin Shekhar Mangar
             Fix For: Trunk, 5.1


Sharing schema and config objects has been known to improve startup performance 
when a large number of cores are on the same box (See 
http://wiki.apache.org/solr/LotsOfCores).Damien also saw improvements to 
cluster startup speed upon caching the index schema in SOLR-7191.

Now that SolrCloud configuration is based on config sets in ZK, we should 
explore how we can minimize config/schema parsing for each core in a way that 
is compatible with the recent/planned changes in the config and schema APIs.
