Pools

• Dummy - Meant for testing, doesn't do anything but complies to it's contract
• Fixed - Spawns a given fixed amount of workers
• Flexible - Spawns workers as a needed basis, given a minimum and maximum it will spawn within those values

Usage

This package pools wyrihaximus/react-child-process-messenger, for basic messaging please see that package for details how to use it.

Creating a pool

This package ships with a set factories:

• Dummy - Creates a Dummy pool
• Fixed - Creates a Fixed pool
• Flexible - Creates a Flexible pool
• CpuCoreCountFixed - Creates a Fixed pool with size set to the number of CPU cores
• CpuCoreCountFlexible - Creates a Flexible pool with max size set to the number of CPU cores

The following example will creates a flexible pool with max size set to the number of CPU cores. Where the create method requires you to give it a React\ChildProcess\Process. The createFromClass lets you pass a classname of a class implementing WyriHaximus\React\ChildProcess\Messenger\ChildInterface that will be used as the worker in the client. Take a look at WyriHaximus\React\ChildProcess\Messenger\ReturnChild to see how that works.

<?php

require 'vendor/autoload.php';

use React\EventLoop\Factory as EventLoopFactory;
use WyriHaximus\React\ChildProcess\Pool\Factory\CpuCoreCountFixed;

$loop = EventLoopFactory::create();

CpuCoreCountFlexible::createFromClass('WyriHaximus\React\ChildProcess\Messenger\ReturnChild', $loop)->then(function (PoolInterface $pool) {
  // Do things with the pool here
});
