Create temporary rows in mysql

Question

Well, I want to do a Flash AS3 Chat.

When the user send a message, the message will be created as a row in mysql with PHP, but if it be so, the mysql server will be very busy, then the row must be temporary.

Someone can help me? ^^' Thanks and sorry for my bad english!

Answer 1

Temporary rows will not solve the problem with your MySQL server being too busy. MySQL can handle many (eg tens of thousands) transactions per second with a pretty normal setup. This article discusses quite a few of the parameters you might be interested in. So, that said, unless you have a TON of traffic on your chat system (and, I mean TONS and TONS) you will probably be ok just using MySQL, saving your rows, fetching your needed rows, and maybe writing a script to purge old rows after a certain date/time. Hope this helps!

Answer 2

If you're on a shared hosting platform, you can make a cron that matches the time. For example;

$db->query("DELETE FROM `messages` WHERE `message_posted` < DATE_ADD(NOW(), INTERVAL 2 HOUR)")

This will delete all the rows with a time two hours more than the current time.

Change the interval for your preference.
