Building a CQRS/ES web application in Elixir using Phoenix

No shit... if you listen to the actual talks, that is EXACTLY what they recommend. Use the patterns where appropriate, don't use it where it's not appropriate. Also consider _where_ the advice came from - finance, gambling, healthcare and so forth.

As for "not production ready" with regards to Event Store specifically, we have had zero reported incidents of data loss which were catastrophic failure of the hardware (or, usually the cloud) it was running on.

One of the projects I worked on was in finance. The fact that we were going to get "a free audit log" from the architecture made everyone so excited.

After the CQRS/ES project failed (I was on cleanup duty) we used a more traditional arch. To handle the audit log we just had a separate table. ("customer" table had "customer_audit" table. Both were written to in transaction. Solved.)

Not production ready - the system, not the database. We never had a problem with the event data stores. The bespoke systems our CQRS/ES rescuees built around it, absolutely.
