If you want to sequentially run ApsaraVideo Media Processing (MPS) jobs based on the job priority and submission order, you can create an MPS queue. Then, when you create a job, specify the priority of the job and associate the job with the MPS queue. Take note that MPS allows you to specify the priority of only specific types of jobs.
Limits
The number of MPS queues that can be created, the features that an MPS queue supports, and the concurrency of an MPS queue vary based on the type of the MPS queue. If you submit jobs to an inappropriate MPS queue, MPS fails to process the jobs. If the number of submitted jobs exceeds the limit for concurrent jobs, the jobs are queued up. For more information, see Overview.
