**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
What outcome are you trying to achieve, ultimately, and why is it hard/impossible to do right now? What is the impact of not having this problem solved? The more details you can provide, the better we'll be able to understand and solve the problem.
Currently, batch supports array jobs with the SEQUENTIAL dependency in order to execute a queue of jobs sequentially. However, the completion of the queue is dependent on every job being successful. A failed job, therefore, will prevent the remaining jobs from running. This feature request is for a way to be able to sequentially run a queue of jobs from beginning to end regardless of whether each job fails or succeeds.

No source files, tests, or implementation entry points are identified; this is a request for AWS Batch behavior. Start by reviewing AWS Batch array jobs and SEQUENTIAL dependency semantics, then define the failure-handling behavior and acceptance criteria for running the queue to completion.
