pgBoss

Leverages PostgreSQL's SKIP LOCKED feature to ensure jobs are processed reliably without duplicates, providing atomic commits as highlighted in the README for guaranteed execution.

Allows jobs to be created within existing database transactions, ensuring data consistency with application logic, a key feature for reliable background processing.

Built-in support for cron expressions enables recurring job scheduling without external tools, simplifying periodic tasks in PostgreSQL-based environments.

Includes priority queues, dead letter queues, and automatic retries with exponential backoff, offering robust job handling for complex workflows.

Provides SQL access for non-Node.js runtimes and works in multi-master setups like Kubernetes, increasing flexibility for polyglot and distributed systems.
