Process Pool

Latest version: pecl install openswoole-25.2.0 | composer require openswoole/core:22.1.5

Manage a pool of Linux worker processes with Swoole. It can be used to manage a group of worker processes to process messages in MQ like Redis or sent from client side. Native Linux commands can also be executed by the pool of processes.

When a process in the pool is terminated, the pool starts a replacement process automatically.
