Camunda 8 helm chart - Elasticsearch

Camunda 8 Topics Discussion & Questions

Hello All,

What is the recommended way to use Elasticsearch with full Camunda 8 stack setup as point of DEV env / PROD env view?
For example in the default settings there is no data node, masterOnly is set to false, and the replicas of master nodes is 2.

master:
## @param elasticsearch.master.masterOnly
masterOnly: false
data:
## @param elasticsearch.data.replicaCount
replicaCount: 0
coordinating:
## @param elasticsearch.coordinating.replicaCount
replicaCount: 0

Thanks

Good question. We have the same question. In our load tests with 5 node cluster and 25 partitions, we observed that the default config leads to errors in elasticsearch nodes. Hence we modified it to masterOnly false, master and data replicaCount to 2. So we have 2 master and 2 data nodes. Not sure if this config is good enough though.
