Global variables - concurrency control

Hi,

I want to use MySQL-Proxy with rw-splitting to disburden our Mysql-Master.
90-95% of the incoming queries are read queries. So I plan to split them to one or more Mysql-Slave-Server.
The new environment should manage 50-80 user connections per second with up to 500 queries per connection.


Are there any known issues with the use of global variables in the lua script?
How are they processed? Is there something like a concurrency control?

Regards

Manuel
