How AI describes PgQueuer

PGQueuer is a minimalist, high-performance Python job queue library built on PostgreSQL, designed to manage queues using LISTEN/NOTIFY for real-time updates. It emphasizes simple integration and efficient concurrency by leveraging PostgreSQL FOR UPDATE SKIP LOCKED and supports batch processing, plus a shared resources context to reuse heavy objects across job executions. The project includes multiple drivers and integrations (PostgreSQL driver, in-memory adapter, PostgREST integration), plus benchmarking, dashboards, metrics, and tracing to build and monitor distributed job scheduling and execution.
