aryan9787/concurrent-job-queue-engine

This is a Spring-based persistent job queue. Clients submit, list, and revive jobs or register workers through REST controllers; workers claim due jobs, dispatch them to type-specific handlers, and report completion or failure. Retry timing and leases support re-execution, while scheduled recovery and load-based scaling maintain worker capacity. The graph follows the sampled service, worker, and repository references; handler execution and some scheduler wiring are represented only where the source index or excerpts support them.
