Varun Thacker commented on SOLR-7191: ------------------------------------- > Restarting a single node takes over two minutes in good circumstance I posted some numbers on SOLR-10265 which you might find helpful. You can run that test on your cluster to see the speed of the overseer. A dedicated overseer node can help you in the meanwhile as well : https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-ADDROLE:AddaRole > Improve stability and startup performance of SolrCloud with thousands of > collections > ------------------------------------------------------------------------------------ > > Key: SOLR-7191 > URL: https://issues.apache.org/jira/browse/SOLR-7191 > Project: Solr > Issue Type: Bug > Components: SolrCloud > Affects Versions: 5.0 > Reporter: Shawn Heisey > Assignee: Noble Paul > Labels: performance, scalability > Fix For: 6.3 > > Attachments: lots-of-zkstatereader-updates-branch_5x.log, > SOLR-7191.patch, SOLR-7191.patch, SOLR-7191.patch, SOLR-7191.patch, > SOLR-7191.patch, SOLR-7191.patch, SOLR-7191.patch > > > A user on the mailing list with thousands of collections (5000 on 4.10.3, > 4000 on 5.0) is having severe problems with getting Solr to restart. > I tried as hard as I could to duplicate the user setup, but I ran into many > problems myself even before I was able to get 4000 collections created on a > 5.0 example cloud setup. Restarting Solr takes a very long time, and it is > not very stable once it's up and running. > This kind of setup is very much pushing the envelope on SolrCloud performance > and scalability. It doesn't help that I'm running both Solr nodes on one > machine (I started with 'bin/solr -e cloud') and that ZK is embedded. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
