When Is a Data Lake Queue Idle?

An idle queue means that there are no SQL job, Flink job, or Spark job running on the queue.

If no job is running within a natural hour, the queue in that natural hour is idle. You will not be charged during idle hours for a pay-per-use queue.

The computing resources of a pay-per-use queue are released after the queue is idle for one hour. When the queue is used again, the computing resources need to be reallocated, which may take 5 to 10 minutes.

Usage is billed by the hour, with any usage less than one hour being rounded up to one hour. The number of hours is calculated on the hour.

For example, if a queue is used during 12:10 to 12:30 or 12:10 to 12:55, the user is charged for one hour.
