Multiple nodes for high availability - everything crashes, and you don't want to loose Elasticsearch and the ability to search and analyze your data. Also for better performance - you can have your index built of many shards that are spread across multiple nodes and have replicas of that shards, so you can physical copies that can handle the traffic if one node is not able to handle it.

| Thank you. In my case I have many client, I use one index by client and a single node. I work with elasticsearch recently and for the moment I don't understand why to use a second node ? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
