Block the user to query not more than once in a second

[dileep ch]

Hi,
I'm very new to mysql database

We use mysql database for to maintain game database. The user should login and play the game. We are facing a problem with one user who kept a scrit and contunously calling api calls. That makes a cpu usage suddenly high. Can we restrict the user by configuring anything like decreasing queries per second, or anything else.

Can do it from web server or from db server.

If yes, please say me how to do it.

note: the user is not db user. i mean he dont have a db user account.

IF there is db account its easy to do.. but this is very new to me..

please help..

Thanks In Advance.
