Elasticsearch Architecture nodes


I have an ECK with 1 kibana + 4 nodes Elasticsearch + 1 Logstash.
I am using hot warm cold rotation.

I would like to change my design.
I would like to change for 1 kibana + 3 nodes HOT + 3 nodes WARM + 3 nodes COLD + 1 Logstash
But normally, I need a master too. 1 Master is enough ?
Do you think it's good as design ?


Hi Chloe,

it is good practice to limit the number of master-eligible nodes in the cluster to three

I'll send you a link to the documentation that might clarify the whole situation.



It is not enough, you need at least 3 master to have a resilient cluster.
