We have a standard MySQL Master/Slave replication for our database. In order to use the slave server we have set up MySQL Proxy. However we have been strongly discouraged to use it as it still alpha and not very well supported.
Our application is built with Drupal 7 which doesn't use very effectively its slave database (see my related question on Drupal Answers).
What tools could we use to act like MySQL proxy and send
SELECT queries on the slave server in order to distribute the load ?
