I worked on implementing ElasticSearch at my company and one of the things they mention clearly is ElasticSearch should NEVER be used as source of truth (primary database).

I think I understand where the OP was coming from.

ElasticSearch + Kibana often gets positioned and used as an open source alternative to Splunk. In that context it is in all respects operating as a primary database since often the source logs are transient.
