Use share identifiers to identify workloads

You can use share identifiers to tag jobs and differentiate between users and workloads. The AWS Batch scheduler tracks usage for each fair share identifier by using the (T * weightFactor) formula, where T is the vCPU usage over time. The scheduler picks jobs with the lowest usage from the share identifier. You can use a fair share identifier without overriding it.

You can set scheduling priority to configure the order that jobs are run in on a share identifier. Jobs with a higher scheduling priority are scheduled first. If you don’t specify a scheduling policy, all jobs that are submitted to the job queue are scheduled in FIFO order. When you submit a job, you can’t specify a share identifier or scheduling priority.
