Creating a Queue

Before executing a job, you need to create a queue.

  • If you use a sub-account to create a queue for the first time, log in to the DLI management console using the main account and keep records in the DLI database before creating a queue.
  • It takes 6 to 10 minutes for a job running on a new queue for the first time.
  • After a queue is created, if no job is run within one hour, the system releases the queue.
