Hi, Is there anything in SolrCloud that would support query-node/shard affinity/stickiness?
What I mean by that is a mechanism that is smart enough to keep sending the same query X to the same node(s)+shard(s)... with the goal being better utilization of Solr and OS caches? Example: * Imagine a Collection with 2 shards and 3 replicas: s1r1, s1r2, s1r3, s2r1, s2r2, s2r3 * Query for "Foo Bar" comes in and hits one of the nodes, say s1r1 * Since shard 2 needs to be queried, too, one of its 3 replicas needs to be searched. Say s2r1 gets searched * 5 minutes later the same query for "Foo Bar" comes in, say it hits s1r1 again * Again shard 2 needs to be searched. But which of the 3 replicas should be searched? * Ideally that same s2r1 would be searched Is there anything in SolrCloud that can accomplish this? Or if there a place in SolrCloud where such "query hash ==> node/shard" mapping could be implemented? Thanks, Otis -- Solr & ElasticSearch Support http://sematext.com/
