Shalin Shekhar Mangar updated SOLR-6554: ---------------------------------------- Attachment: SOLR-6554.patch Here's a better patch which takes care of some of the nocommits: # The live nodes information is read from the ZkStateReader's cluster state because the one in ZkStateWriter's cluster state might be stale # We force refresh the clusterstate once at the beginning of the loop and then only if there's an error in the main loop. # Added a simple TestClusterStateMutator, I'll add more. I still have a few ideas I'd like to try. > Speed up overseer operations for collections with stateFormat > 1 > ----------------------------------------------------------------- > > Key: SOLR-6554 > URL: https://issues.apache.org/jira/browse/SOLR-6554 > Project: Solr > Issue Type: Improvement > Components: SolrCloud > Affects Versions: 5.0, Trunk > Reporter: Shalin Shekhar Mangar > Attachments: SOLR-6554.patch, SOLR-6554.patch > > > Right now (after SOLR-5473 was committed), a node watches a collection only > if stateFormat=1 or if that node hosts at least one core belonging to that > collection. > This means that a node which is the overseer operates on all collections but > watches only a few. So any read goes directly to zookeeper which slows down > overseer operations. > Let's have the overseer node watch all collections always and never remove > those watches (except when the collection itself is deleted). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
