AWS Batch's ListJobs API now returns a statusSummary field for Array Jobs, showing child job counts across all states (SUBMITTED, PENDING, RUNNABLE, STARTING, RUNNING, SUCCEEDED, FAILED) in a single call. Previously, this information required using the DescribeJobs API. The response also includes a statusSummaryLastUpdatedAt timestamp for freshness tracking. This enhancement reduces API calls needed to monitor large-scale parallel workloads and is available in all AWS Regions where AWS Batch operates.
