With replication, there is only one writeable node.
How do you force
mediawiki to do reads from replica #n and writes to the master?
Code that works with the database asks the load balancer for a database
connection object that's either the master (for write or time-sensitive read
work) or a randomly selected not-too-lagged slave (for non-sensitive read work).
See LoadBalancer.php.
