I have a simple redis installation and it seems to slowly eat more and more ram at a steady incline until I restart the redis server.
I'm using redis as a caching layer, currently I don't set an expire on my keys as I didn't think that was necessary. I thought redis would drop off old keys or something - though clearly this isn't happening.
Whats the best way of handling this kind of situation, should I set a short expire time on my keys or is there some functionality built into redis to expire old keys to make room for new ones?
Thanks in advanced!
