-- Use one of the following lenses to modify other fields as desired:
--
-- * 'ujqState' - Describes the queue's ability to accept new jobs.
--
-- * 'ujqPriority' - The priority of the job queue. Job queues with a higher priority (or a higher integer value for the @priority@ parameter) are evaluated first when associated with same compute environment. Priority is determined in descending order, for example, a job queue with a priority value of @10@ is given scheduling preference over a job queue with a priority value of @1@ .
--
-- * 'ujqComputeEnvironmentOrder' - Details the set of compute environments mapped to a job queue and their order relative to each other. This is one of the parameters used by the job scheduler to determine which compute environment should execute a given job.
--
-- * 'ujqJobQueue' - The name or the Amazon Resource Name (ARN) of the job queue.
