Yeah. I'd prefer 2 nodes on the same machine but using that: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-cluster.html#allocation-awareness So primaries and replicas are not allocated on the same machine.
You could also add a 3rd node (master only - 512Mb/1Gb max) Best -- David Pilato | Technical Advocate | Elasticsearch.com @dadoonet | @elasticsearchfr Le 3 septembre 2014 à 18:40:27, vineeth mohan ([email protected]) a écrit: Hi , I am not sure if there is anything related to ES that makes a high RAM problematic , but in general very high memory is not advised in java systems. One of the reasons being the cobra effect which stems from the fact that garbage collection might need more time for higher memory.

If my server have about 64G ram. This seems a perfect. But what If I have a server with 128G RAM and sufficient CPU's. Which configuration is better a) two nodes on server each with ES_HEAP_SIZE say about 31G. b) one node on the server with ES_HEAP_SIZE say 64G.
