Distributed lock lacks expiration

Code reviewConcurrencySenior–Staff~30 min

1def process_job(job_id):

2 lock = redis.set(f"lock:{job_id}", "1", nx=True)

3 if not lock:

4 return

5 try:

6 do_work(job_id)

7 finally:

8 redis.delete(f"lock:{job_id}")

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
