Having just an Elasticsearch index without also having the data in a primary store like a RDMS is an anti-pattern and not recommended by almost all experts. Whether you want to call it a “system of record”, i wont argue semantics. But the point is, its recommended hacing your data in a primary store where you can index into elasticsearch.

Have you a link for this? Never heard of this requirement (but not an elastic user so no surprise).
