mysql twitter/facebook like status feed
- by barjonah
Hi, I have two tables. One named status like this...
user_id | status
--------+-----------
1 | random status from user 1
2 | random status from user 2
3 | random message from user 3
4 | staus from user 4
1 | second status for user1
etc...
and another named users_following like this...
user_id | is_following
--------+-----------
1 | 2
1 | 3
2 | 1
3 | 2
meaning that user 1 is following both users 2 and 3 etc...
So, let's say I chose user 1. What is the best query (performance wise) to show the status updates of users that user 1 is following, in this case users 2 and 3
currently I have something like
SELECT * from status WHERE user_id IN(SELECT is_following FROM users_following
WHERE user_id='1') LIMIT 0,5
but I don't think this is good for performance if a user was following thousands+ of users
