MySQL Proxy is a simple and new program that sits between your client and MySQL server(s) that can monitor, analyze or transform their communication. Its flexibility allows for a wide variety of use cases, including:
a) Load balancing
b) Failover
c) Query analysis
d) Query filtering and modification
e) and many more...
MySQL Proxy tutorial
Oreilly has published a nice tutorial using MySQL proxy application:
MySQL Proxy is a lightweight binary application standing between one or more MySQL clients and a server. The clients connect to the Proxy with the usual credentials, instead of connecting to the server. The Proxy acts as man-in-the-middle between client and server.
In its basic form, the Proxy is just a redirector. It gets an empty bucket from the client (a query), takes it to the server, fills the bucket with data, and passes it back to the client.
If that were all, the Proxy would just be useless overhead. There is a little more I haven't told you yet. The Proxy ships with an embedded Lua interpreter. Using Lua, you can define what to do with a query or a result set before the Proxy passes them along.

Anyone tested this already? Sounds relly nice, but seems to be very new software…
Yes, anyone out there who have tested this? espcialy on a set of freebsd servers?
I have tested on a lab and it works fine. Itś a new software and have something to improve.
mysql-proxy which running on freebsd 7.2 not open a port
anyone tested proxy + replication and read-only / read-write back-ends ?
actually i wanna try this for my final project undergraduate
but is it possible to create load balancer based on performance from database server using this one? :)
i jus try it this week and i think that is a great software and a easy one to perform a load balanced cluster, but mysql-proxy works with lua scripts and only works with one each time, you need to learn hot to program in lua to make a failover, load balanced cluster with mysql-proxy only..
mysql-proxy can be great but it needs more time and development.
