Just an observation: Are you sure that you don’t want to allow your users to have multiple sessions? You made users
uniqueacross the entire table, which mean there can only ever be one session for a user. Unless you delete ‘expired’
sessionsASAP, users won’t be able to start a new session again after their original session expired.
That may be desirable for your application and thus intended, but perhaps it was not?
