-----------------------------------
Summary: CloudSolrClient with HTTP ClusterState shouldn't
time-expire recently used cache entries
Key: SOLR-17520
URL: https://issues.apache.org/jira/browse/SOLR-17520
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud, SolrJ
Reporter: David Smiley
When using CloudSolrClient with HTTP URLs to Solr for the cluster state:
CloudSolrClient caches a collection's state (DocCollection) for a limited time
in ExpiringCachedDocCollection. It doesn't matter how frequently/recently this
collection is used; it'll expire anyway. I think instead, the expiration
should keep getting pushed back on each use so that we don't needlessly ask
Solr for the DocCollection every ~minute. The possible stale-ness of a
DocCollection shall be handled by existing "stateVer" mechanisms.
