Large database design


Just a short question, about how you would do this:

Let's say I have 1 million users, and i need to store data about this user, like success_logins, attempts, remember_tokens, email_confirmations and so on

Would you make one table for every one OR would you make a usermeta with user_id, key,value with user_id and key is indexed - Wich will be best in the long run?

Well, the 2nd one would only be useful if your schema can change during runtime,

Otherwise, I'd stick to explicitly defined tables/columns

Performance-wise, i dont think there will be substantial difference (but that's just an educated guess, presuming innodb and sane queries)

I would say any data you're only storing 1 of, keep in the user record. So if there is only 1 remember token, 1 email confirmation, keep it in the user record. If you need to track multiple tokens or other datum, normalize that out into another table.
