I want to emphasize that if you use redis as intended (as a slightly-persistent, not-HA cache), it’s great. Unfortunately, more and more shops seem to be thinking that Redis is a full-service database and, as someone who’s had to spend an inordinate amount of time maintaining such a setup, it’s not. If you’re writing software and you’re thinking “hey, it would be easy to just put a SET key value in this code and be done,” please reconsider. There are lots of great products out there that are better for the overwhelming majority of use cases.
Ouch. (via Aphyr)(tags: redis storage architecture memory caching ha databases)
