Can you have multiple nodes in elasticsearch cluster?
- A running instance of Elasticsearch that belongs to a cluster. Multiple nodes can be started on a single server for testing purposes, but usually you should have one node per server. Each document is stored in a single primary shard. When you index a document, it is indexed first on the primary shard, then on all replicas of the primary shard.
- Logstash and the Elasticsearch cluster receiving the logs do not have to be of the same version, but not all versions are compatible with each other. To learn more about supported Logstash versions, see Support Matrix. For production systems, these examples need to be modified further.
We have database to store data in to it. We prefer to have database over FPS because they handle the data efficiently.
- We chose Elasticsearch cause of how it indexes data, the analyzers we can use and also the ability to use the nested and parent-child data in it, but we mainly chose it because of the analytical queries it can do.
