I’ve installed Zammad and Elasticsearch in a develpment vps to test. Reading Zammad installation doc, please correct me if I am wrong, I couldn’t see any reference for Elasticsearch in production. So, I’d like to get some experience from you about both in production.
I think Elasticsearch needs, at least, 3 nodes to proper distribute shards/replicas, avoid a situation called “split-brain” and data loss. Elasticsearch doc, https://www.elastic.co/guide/en/elasticsearch/reference/current/system-config.html#dev-vs-prod, recommends some configs before go to production.
Is it really necessary to work with Zammad?
Thanks for some advice.
