autoslave 7.x-1.9

Autoslave is a must-have module for increasing server availability/reliability scalability and performance when using a clustered db backend. If your master db server goes down, autoslave keeps you up by automastering to either master2 or autoslaving to a slave automatically (depending on configuration). Reads will happen from slaves, writes to master1 or master2. When cron runs, the server status is verified to see if the master1 is back up again and will automatically bring it back into action. Meanwhile, your site stays up and doesn't miss a beat. The ultimate setup for scalability, reliability and availability.
