Increase redis priority of session cache

[pefoley2]

If the redis cache fills up, we want to drop everything else before sessions.

Take a look at http://redis.io/topics/lru-cache

https://github.com/tjcsl/ion/tree/redis should handle the lack of dropping sessions. I'm not at all sure that it will properly garbage collect and/or cleanup invalid sessions though.

I'm not at all sure this is needed, and even if it is, i'll need to be well tested. Relevant diff is below: diff --git a/intranet/settings/init.py b/intranet/settings/init.py index 7e929e5..d973a6d 100644 --- a/intranet/settings/init.py +++ b/intranet/settings/init.py @@ -330,7 +330,8 @@ if not TESTING: SESSION_REDIS_DB = 0 SESSION_REDIS_PREFIX = VIRTUAL_ENV + ":session"

• No TTL means redis doesn't evict sessions in low memory situations.

• SESSION_COOKIE_AGE = None # type: int SESSION_SAVE_EVERY_REQUEST = True

@pefoley2 do you know if this is still an issue?

Haven't seen any redis problems. Closing.
