kumo.on('get_queue_config', function(domain, tenant, campaign, routing_domain))

!!! note This event handler is in flux and may change significantly

Not the final form of this API, but this is currently how we retrieve configuration used for managing a queue.

The parameters correspond to the domain, tenant, campaign and routing_domain fields from the scheduled queue name, as discussed in Queues.

kumo.on(
  'get_queue_config',
  function(domain_name, tenant, campaign, routing_domain)
    return kumo.make_queue_config {
      max_retry_interval = '20 minutes',
    }
  end
)

See also kumo.make_queue_config.

{{since('2023.11.28-b5252a41', indent=True)}} It is now possible to use kumo.on to register multiple handlers for this event. The handlers will be called in the order that they were registered. If a handler returns nil then the next handler will be called. Conversely, if a handler returns a queue configuration object, no further handlers will be called.

This behavior is intended to make it easier to compose multiple helpers
or lua modules together.
