ReactPHP bindings around ext-parallel-infinite-pool

Install

To install via Composer, use the command below, it will automatically detect the latest version and bind it with ~.

composer require react-parallel/infinite-pool 

Usage

The following example will spin up a thread with a 1 second TTL clean up policy. Meaning that threads are kept around for 1 second waiting for something to do before closed. It then runs a closure in the thread that will wait for one second before returning an message. Upon receiving that message the mean thread will echo out that message before closing the pool;

use React\EventLoop\Factory;
use ReactParallel\EventLoop\EventLoopBridge;
use ReactParallel\Pool\Infinite\Infinite;

$loop = Factory::create();
$infinite = new Infinite($loop, new EventLoopBridge($loop), 1);
$infinite->run(function () {
    sleep(1);

    return 'Hoi!';
})->then(function (string $message) use ($infinite) {
    echo $message, PHP_EOL;
    $infinite->close();
});
$loop->run();

Metrics

This package supports metrics through wyrihaximus/metrics:

use React\EventLoop\Factory;
use ReactParallel\EventLoop\EventLoopBridge;
use ReactParallel\EventLoop\Metrics as EventLoopMetrics;
use ReactParallel\Pool\Infinite\Infinite;
use ReactParallel\Pool\Infinite\Metrics;
use WyriHaximus\Metrics\Configuration;
use WyriHaximus\Metrics\InMemory\Registry;

$loop = Factory::create();
$registry = new Registry(Configuration::create());
$eventLoopBridge = (new EventLoopBridge($loop))->withMetrics(EventLoopMetrics::create($registry));
$finite = (new Infinite($loop, $eventLoopBridge, 1.3))->withMetrics(Metrics::create($registry));
