Best configuration for a 4 hosts cluster

Elastic Stack Elasticsearch
1

Hi,

I am about to start a new ES cluster that will index 250Gb(500M docs) spread around ~10 indices.

I have four hosts available and was wondering what the best cluster setup for this would be?

I though about doing this:

Node1 : node.data=false, node.master=false
Node2 : node.data=true, node.master=true
Node3 : node.data=true, node.master=true
Node4 : node.data=true, node.master=true

And then set minimum_master_nodes=2 on all nodes, is this ok?

BR,
Sven

Yes, it's a safe configuration. It's not obvious that having a separate client node in a four-node cluster gives the best bang for the buck, but it depends on your query load. I suggest you do some measurements.

Ok thanks!
