Question

The website I’m create has “Events”. Events have a title, date, and the userids of the people involved. An event can be anything from following someone, creating a new post, etc. I was thinking of storing all events in a single table, but I could see this getting very big very quickly.

Am I doing it right? When I need to search the table for, say, event pertaining to a certain user, how bad of a toll would that be on the system? Could I optimise it somehow?

Answer 1

You would add indexes on the columns you most frequently use in WHERE clauses, e.g. if you are frequently selecting all events that pertain to a certain user, you should create an index on the user_id column.
