Thank you for the article.

My own conclusions from your data:

- Under light workloads, you can get away with Postgres. 7k RPS is fine for a lot of stuff.

- Introducing Redis into the mix has to be carefully weighted against increased architectural complexity, and having a common interface allows us to change that decision down the road.

Yeah maybe that's not up to someone else's idea of a good synthetic benchmark. Do your load-testing against actual usage scenarios - spinning up an HTTP server to serve traffic is a step in the right direction. Kudos.
