Named queues

The App Engine Task Queue provides a single default queue for all App Engine applications. Additional queues may be configured by providing a queue.yaml configuration file. This allows developers to define one or more custom push queues, along with configurations for things like retry logic and rate of execution.

The queue.yaml configuration file is as follows:

queue:
- name: example-one
  target: service-one
  rate: 10/s
  retry_parameters:
    task_retry_limit: 5
- name: example-two
  target: version-x.service-two
  rate: 5/s

The second queue definition target takes the form of <version>.<service>. This format can be used to specify a target version of a given service for tasks to be delivered to.
