Instance Attribute Details

#drain_lock_key ⇒ Object

Redis key used for the distributed drain lock. The scheduler acquires this lock (SET NX) before enqueueing DrainJob; the job releases it immediately on start so new work arriving mid-drain gets its own job on the next tick. Set to nil to disable lock management entirely.
