AWS Batch Gets Bulk Job Control—Cancel 50 Jobs at Once
AWS Batch now lets you cancel or terminate up to 50 jobs with a single API call through new CancelJobs, TerminateJobs, and TerminateServiceJobs endpoints. This cuts down operational overhead when managing large-scale workloads, and you'll get per-job results back instantly—plus better job lifecycle tracking with new isCancelled and isTerminated fields in ListJobs.
