Redis is fast - I'll cache in Postgres

There are books & many articles online, like this one arguing for using Postgres for everything. I thought I’d take a look at one use case - using Postgres instead of Redis for caching. I work with APIs quite a bit, so I’d build a super simple HTTP server that responds with data from that cache. I’d start from Redis as this is something I frequently encounter at work, switch it out to Postgres using unlogged tables and see if there’s a difference.

I agree with the author. If you are already using Postgres as your database, then using it also as your cache initially should be ok, rather than dealing with different dependencies.
