View Source Roger.Partition.Worker (roger v3.2.1)
Handles the decoding and execution of a single job.
Besides running the job, various administrative tasks need to be performed as well, namely:
Check whether the job has not been cancelled in the meantime
Check whether another job is currently running with the same execution_key, and if so, delay this current job until the currently running one finishes
On job failure, the job needs to be queued in the retry queue, if the job is marked retryable. By default, jobs are not retried.
