Uber runs a lot of databases in production. We stopped using Postgres a while ago for new applications that talk SQL, and this article explains some of the reasoning.

We still have many applications that talk directly to MySQL, and we still have our original API monolith that talks directly to Postgres.

All new applications are being built using distributed databases like our in-house Schemaless system which happens to be backed by MySQL, and we also have Riak and Cassandra in production.

I would love to see a similarly detailed write-up on your guys' transition from Riak to Cassandra. Especially considering you would have been really, really deep into the details and guts of operating Riak at the red-line from your time at Voxer.

Will Schemaless ever be released open source? It sounds great...

Does Uber still use Python for backend services?
