I am consdering to move "ulogs" out of redis and into files because of the potential memory usage - perhaps a hybrid approach where only new logs are in redis would work best. I don't have a definitive solution yet. However, this would be a problem when handling tens of thousands of users or more, which makes it a problem I'd love to have! I'm also considering letting users delete their own history of logins that are older than N days, since it's their data in the end, not mine.
