Don't feel bad. I recently worked on a website that would retrieve data exclusively from Redis. The problem was, whoever wrote the thought that Redis calls were free. It would make thousands of Redis calls in a single request... for the same data.
Lol redis is so good it’s always abused. Did you guys end up pipelining the requests?
… in this case I was grabbing the user 3 times, thinking that because it’s a primary key lookup it’d be fast, but it was ~30ms in some cases. Probably because Postgres’ cache is otherwise full or getting invalidated.
