Sharded Interval Queue

Sharded Interval Queue v2.0.0 is a zero-dependency, persistent store sharded queue that runs async functions in timed intervals while preserving ordering across shards. It supports in-memory, LowDB, and Redis adapters for persistence and scaling. V2 introduces job limits to cap concurrent running jobs. Key differentiator: sharded design allows multiple queues to coordinate under a single name, with no recurring intervals or hooks—execution starts on job add. Decorator and thunk patterns are supported for wrapping async jobs. Suitable for rate-limited scheduling with ordering guarantees.
