Is there anyway to create a Redis database where keys HAVE TO expire after a certain time? I know I can expire an individual key using the EXPIRE command but since I am expiring every key after a certain time anyways, it would be nice to have this behavior specified in the Redis config file.

No, Redis (up to and including v3.2) does not provide the means for automatically setting the TTL of newly-created keys. You have to set it explicitly for each key you create.
