I've got a fairly large document set (~1B) and want to organize things in a performant fashion with enough replication to make me happy. The general configuration: 3 indexes 50 shards X nodes - all AWS What I would like to do is configure this using the cluster zone/nodes in such a way that I can have: N - persistent nodes - contain the whole collection of docs (fewer nodes, slower, more storage) M - query nodes - insure that only one replica is on each of these nodes I'm pretty sure that this is do-able with the zones/nodes but didn't quite figure it out. Is the following correct: Set : node.rack\_id : persist node.group: persist and/or node.rack\_id : query node.group: query Then set: /\_settings index.routing.allocation.include.group1 : persist index.routing.allocation.include.group1 : query cluster.routing.allocation.awareness.attributes : rack\_id Does the above work, before I try it? If there is anything else in terms of advice that would be useful? Thanks, David -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
