ASF subversion and git services commented on SOLR-6521: ------------------------------------------------------- Commit 1653801 from [~noble.paul] in branch 'dev/branches/lucene_solr_5_0' [ https://svn.apache.org/r1653801 ] SOLR-6521 CloudSolrServer should synchronize cache cluster state loading > CloudSolrClient should synchronize cache cluster state loading > -------------------------------------------------------------- > > Key: SOLR-6521 > URL: https://issues.apache.org/jira/browse/SOLR-6521 > Project: Solr > Issue Type: Improvement > Components: SolrCloud > Reporter: Jessica Cheng Mallet > Assignee: Noble Paul > Priority: Critical > Labels: SolrCloud > Fix For: 5.0, Trunk > > Attachments: SOLR-6521.patch, SOLR-6521.patch > > > Under heavy load-testing with the new solrj client that caches the cluster > state instead of setting a watcher, I started seeing lots of zk connection > loss on the client-side when refreshing the CloudSolrServer > collectionStateCache, and this was causing crazy client-side 99.9% latency > (~15 sec). I swapped the cache out with guava's LoadingCache (which does > locking to ensure only one thread loads the content under one key while the > other threads that want the same key wait) and the connection loss went away > and the 99.9% latency also went down to just about 1 sec. -- 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
