If Elasticsearch is at the end of an ETL pipeline, does that mean that if Elasticsearch gets corrupted you can rebuild it by re-running the pipeline?

If so I wouldn't call this a "primary data store", since durability isn't critical.

The article says:

> After drafting many blueprints, we went for a Java service backed by Elasticsearch as the primary storage! This idea brought shivers to even the most senior Elasticsearch consultants hired

I'll shiver if Elasticsearch corrupting irreversibly loses data, but if it can be rebuilt from another source I don't see any problems with it at all.
