Manuel Lenormand updated SOLR-5501: ----------------------------------- Comment: was deleted (was: Set hot/cold replica on a replica basis in clusterstate.json through the collection admin API) > Ability to work with cold replicas > ---------------------------------- > > Key: SOLR-5501 > URL: https://issues.apache.org/jira/browse/SOLR-5501 > Project: Solr > Issue Type: Improvement > Components: SolrCloud > Affects Versions: 4.5.1 > Reporter: Manuel Lenormand > Labels: performance > Fix For: 4.7 > > > Following this conversation from the mailing list: > http://lucene.472066.n3.nabble.com/Proposal-for-new-feature-cold-replicas-brainstorming-td4097501.html > Should give the ability to use replicas mainly as backup cores and not for > handling high qps rate. > This way you would avoid using the caching ressources (solr and OS) used when > routing a query to a replica. > With many replicas it's harder hitting the solr cache (same query may hit > another replica) and having many replicas on the same instance would cause a > useless competition on the OS memory for caching. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
