 This has been well tested using a MySQL database.
 There are several benefits of Multi-master mode:
 
-  * You can have large numbers of build slaves handling the same queue of build requests.
-    A single master can only handle so many slaves (the number is based on a number of factors including type of builds, number of builds, and master and slave IO and CPU capacity--there is no fixed formula).
-    By adding another master which shares the queue of build requests, you can attach more slaves to this additional master, and increase your build throughput.

 Because of this shared state, you are strongly encouraged to:
 
-  * Ensure that each named scheduler runs on only one master.
-    If the same scheduler runs on multiple masters, it will trigger duplicate builds and may produce other undesirable behaviors.
