Hi. I'm going to setup a new elasticsearch cluster like below data and coordinator node spec.
- Broadwell E5-2630 v4 2P10C CPU, 64GB RAM, 4.8TB SSD.
There are 30 nodes for data-node and 3 nodes for coordinator-node.
I want to setup master nodes at least 3 nodes as VM in a Kubernetes environment.
I know the master node doesn't need to high spec because it only manages cluster environment, not performance.
How can I estimate the proper specs for the master nodes of my cluster?( I will struct 3 nodes for master nodes.)
- More nodes in a cluster, do I need more specs for a master node?
- If then, what is the spec that I need for a master node? RAM? CPU? DISK? NIC?
