### Failover
-In *failover* mode, multiple consumers can attach to the same subscription. In
failover mode, the broker selects the master consumer based on the priority
level and the lexicographical sorting of a consumer name. If two consumers have
an identical priority level, the broker selects the master consumer based on
the lexicographical sorting. If these two consumers have different priority
levels, the broker selects the consumer with a higher priority level as the
master consumer. The master consumer is initially the only one receiving
messages. When the master consumer disconnects, all (non-acknowledged and
subsequent) messages are delivered to the next consumer in line.
