Hi, There is an excellent question asked about two years ago that was never properly answered: https://groups.google.com/forum/#!topic/elasticsearch/dxjpMd4vNXQ
I have the exact same question. I've got a cluster with a lot of data nodes plus two nodes that act as master + client nodes (no data). For now I'm using those two nodes for both master (shard/cluster management) tasks and client tasks (query handling). I've seen a big performance gain when querying the client nodes, compared to querying my very busy data nodes directly. But I'd still like to get your view on the hardware requirements of the master/client nodes. Is RAM important for serving the query results, or is most RAM-heavy tasks performed by the data nodes? And similarly, is CPU important on the client nodes? Thanks, Lasse -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
