But that is his point. If you cannot find the session id in redis, you login again. If your Redis server crash, you start a new one and everyone just login again. No data is lost.

Sure the data is lost. A session commonly holds arbitrary state, and even if it’s just the login information. This is ridiculous.

If you consider it important, you have to store it in a real database. No buts. If you don't consider it important, sharded redis works fine.

		Redis is a real database. If I wasn’t convinced it could retain data I hand it, I wouldn’t use it in the first place. Just because it works for your use case right now doesn’t mean there isn’t room for improvements to support others too.
