Re: [PHP-DB] MySQL Clustering, redundancy
Yes,it's called Replication in the MySQL documentation. However, since the info in the manual is kind of sparse so I would hop on google and do a search for specific instructions on how to do it when your ready, but to answer your question, yes, MySQL does do Redundancy/Failover. (Ofcourse you must take account of this in your code interacting with the server, but the data will be sync'd).

RE: [PHP-DB] MySQL Clustering, redundancy
Thanks for your response Adam! Do you know if there is any way MySQL can be spread across multiple machines? I am looking at a huge application for a client, that will need to support thousands of simultaneous users. I am wondering if MySQL can handle load like that. That's why I was asking about clustering MySQL servers for the ability to handle more users simultaneously. Has anyone had any experience with a large scale application on MySQL?

RE: [PHP-DB] MySQL Clustering, redundancy
I have never actually tried to program against something which talks to multiple DB's, the quickest way would be in your DB connection code to have something that will either: A. Try the first DB and connect to the second if it's down. B. Randomly choose a SQL server. The most fluid solution I could think of would be an application gateway of some sort which will load balance properly to different IP's while in your code you only point to one.
