Well, we can actually do persistent storage in the ocp4 cluster. ;)
Oh, that's interesting! Are we using it already in one of our ansible-deployed apps?
I'm not sure how slow/fast it might be, but it is there...
I think it's fine, Redis will use memory first and snapshot to disk periodically, so disk speed should not be an issue. That said, now that I look more into the docs it means that if I try to store more data than what the memory allows, it'll evict data and not use the disk for that. So having persistent storage for Redis only helps with pod restarts. Which is still useful.
