AWS Batch now supports alerts to detect and react to jobs stuck in RUNNABLE state

Starting today, AWS Batch now supports a Batch Job Queue Blocked CloudWatch Event for jobs stuck in RUNNABLE state. Customers can automate actions using EventBridge to be able to take an action on these stuck jobs. Additionally, customers can configure jobStateTimeLimitActions parameter from the CreateJobQueue and UpdateJobQueue APIs to terminate the stuck job unblocking the jobs behind it within the queue.
