Updated May 24, 2026
Short answer
Worker pool architecture manages concurrent PHP processes to efficiently process background jobs with controlled resource usage.
Deep explanation
Worker pools are essential in PHP systems handling high-throughput asynchronous workloads such as queues, batch jobs, and event processing.
Core components:
- Master process
- orchestrates worker lifecycle
- Worker processes
- execute jobs independently
- Job queue
- Redis, RabbitMQ, Kafka
Design patterns:
- pre-fork model
