​BullMQ is a Node.js library that implements a fast and robust queue system built on top of Redis, designed to address various challenges in modern microservices architectures. It is structured around four primary classes. BullMQ offers features like minimal CPU usage due to a polling-free design, distributed job execution based on Redis, support for both LIFO and FIFO jobs, job priorities, delayed and scheduled jobs according to cron specifications, automatic retries of failed jobs, concurrency settings per worker, sandboxed processing functions, automatic recovery from process crashes, and parent-child job dependencies. These capabilities make BullMQ a powerful tool for building scalable and reliable job processing systems in Node.js applications.
