Job states

A job is a row in akadze.jobs. Its state is one of five values.

stateDiagram-v2
    [*] --> queued: enqueue
    queued --> running: claim
    queued --> cancelled: cancel requested / expired
    running --> succeeded: body returned
    running --> queued: error, timeout, Retry, Snooze, shutdown, rescue
    running --> failed: attempts used up, Fail
    running --> cancelled: Cancel, or cancel requested and the body raised
    failed --> queued: requeue
    succeeded --> [*]
    failed --> [*]
    cancelled --> [*]

State	Meaning
queued	waiting; ready once run_at has passed
running	claimed by a worker that holds the lease
succeeded	the body returned a JSON value (or nothing); result holds it
failed	out of attempts, or Fail; errors holds the latest failures (the last 10 run errors, plus lost-worker entries)
cancelled	cancelled before or during a run

Finished rows are deleted after the app's retention (default 7 days).

Useful columns: attempt (attempts spent), max_attempts, run_count (claims so far, used for fencing), snoozes, run_at, priority, unique_key, limit_key, meta, worker_id, cancel_requested_at, expires_at, finished_at.
