2 Servers with 2 primary shards... optimization questions
With this set up: Server1Server2 Primary Shard 1 Primary Shard 2 Replica Shard 1 Replica Shard 2 1) If primary shard 1 failed, would replica shard 1 take over and become primary shard 1? 2) Is reading performance optimized from 2 primary shards on 2 separate severs? 3) With documentation stating we would end up with two nodes having one shard each, and one node doing double the work with two shardsspecifically the one node doing double the work with two shardsdo they mean 1 server having a primary shard and a replica shard? -- Also, Server1Server2 Primary Shard 1 Primary Shard 2 Replica Shard 2 Replica Shard 1 1) is this set up possible and would it be beneficial? If so, would I have to manually assign the shards or is this how ES does it default wise with 2 servers and 2 shards? 2) with this set up...if it is even possible...is there a read performance from having Primary Shard 1 on server 1 and having Replica Shard 1 on server 2? -- You received this message because you are subscribed to the Google Groups elasticsearch group.

Which ES cluster would give better performance? 1 shard 2 replicas or normal 2 shards

On http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/replica-shards.html in Figure 52. Adjust the number of replicas to balance the load between nodes they show Node 3 which contains only 2 replica shards. They state in it The fact that node 3 holds two replicas and no primaries is not important.
