The queue defines a hierarchy of resources that consume tasks from queues:
Provisioners, identified with a
provisionerId, are responsible for groups of worker types. While some
provisioners, such as the AWS provisioner, are active software components,
others are simply identifiers within the Queue service's data structures. For
example, there is no active management of the
Provisioners can be declared, and metadata associated with them, via the declareProvisioner API method.
Worker Types, identified by
provisionerId/workerType, are nested under a single provisioner and gather
interchangeable workers that can all perform the same work. Tasks are queued
for a specific worker type, and workers claim work for a single worker type.
Worker types can be declared, and metadata associated with them, via the declareWorkerType API method.
Workers are the entities that actually
perform work, and are identified by
workerGroup/workerId. A worker claims and
performs work from a single worker type.
Workers can be declared, and metadata associated with them, via the declareWorker API method.
