max_message_rate

Optional string.

Specifies the maximum permitted rate at which messages can be delivered from this source to the corresponding destination site.

The throttle is specified the same way as for max_connection_rate above.

If the throttle is exceeded and the delay before the current message can be sent is longer than the idle_timeout, then the messages in the ready queue will be delayed until the throttle would permit them to be delievered again.

This option is distinct from the scheduled queue max_message_rate option in that the scheduled queue option applies to a specific scheduled queue, whilst this egress path option applies to the ready queue for a specific egress path, through which multiple scheduled queues send out to the internet.

If you have configured max_message_rate both here and in a scheduled queue, the effective maximum message rate will be the lesser of the two values; both constraints are applied independently from each other at different stages of processing.
