> Consider a case where the user job depends on some external entity/service like a database
or a web service. If the service needs restart or encounters a failure, the user should be
able to pause the job and resume only when the service is up. This will be better than re-executing
the whole job. Hence there should be some way to pause/resume jobs (from web-ui/command line)
etc.
