Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 155 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Does the system have to do a COUNT(*) query on the user's votes for the day, then determine if the daily limit is reached? Or is there another method to doing this?

Is this really relevant? – alex Jan 17 '11 at 17:23

@alex: not to the operation of SO, but perhaps to the learning of anyone interested. – John Jan 17 '11 at 18:25
    
@John Then it really should belong to SO. – badp Jan 24 '11 at 16:35

@badp: "Belong to SO"? Do you mean "belong on SO"? According to the FAQs, questions about the core Stack Exchange engine that powers all Stack Exchange websites are welcome here. – John Jan 24 '11 at 17:28

We do exactly what you describe.. we count(*) for utc today on the existing votes every time you vote, and when you hit the limit, we tell you to come back in (n) hours to vote more!

If you're asking if there's another way to do so, then obviously yes.

In the user table, add a column for each vote limit. Reset the columns every night to the appropriate vote allowance. Decrement the value every time you use a vote. Check the value to know how many votes are left.

Similarly, for rate limited actions, add a column with the timestamp of the last time you changed something. Do a date diff to know how much time has passed and deny or allow accordingly.

Is this what SE does? I don't know. It might be. It might not. I have never really done databases, so I don't know how horrible this idea is.
