Installation
To install via Composer, use the command below, it will automatically detect the latest version and bind it with ~
.
composer require wyrihaximus/react-child-process-pool
Pools
Dummy
- Meant for testing, doesn't do anything but complies to it's contractFixed
- Spawns a given fixed amount of workersFlexible
- 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, which create different pools. (All the options in the following examples are the default options.)
Dummy
Creates a Dummy
pool:
$loop = EventLoopFactory::create(); Dummy::createFromClass(ReturnChild::class, $loop)->then(function (PoolInterface $pool) { // Now you have a Dummy pool, which does absolutely nothing });
Fixed
Creates a Fixed
pool:
$loop = EventLoopFactory::create(); $options = [ Options::SIZE => 5, ]; Fixed::createFromClass(ReturnChild::class, $loop, $options)->then(function (PoolInterface $pool) { // You now have a pull with 5 always running child processes });
Flexible
Creates a Flexible
pool:
$loop = EventLoopFactory::create(); $options = [ Options::MIN_SIZE => 0, Options::MAX_SIZE => 5, Options::TTL => 0, ]; Flexible::createFromClass(ReturnChild::class, $loop, $options)->then(function (PoolInterface $pool) { // You now have a pool that spawns no child processes on start. // But when you call rpc a new child process will be started for // as long as the pool has work in the queue. With a maximum of five. });
CpuCoreCountFixed
Creates a Fixed
pool with size set to the number of CPU cores:
$loop = EventLoopFactory::create(); CpuCoreCountFlexible::createFromClass(ReturnChild::class, $loop)->then(function (PoolInterface $pool) { // You now have a Fixed pool with a child process assigned to each CPU core. });
CpuCoreCountFlexible
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.
$loop = EventLoopFactory::create(); CpuCoreCountFlexible::createFromClass(ReturnChild::class, $loop)->then(function (PoolInterface $pool) { // You now have a Fixed pool with a child process assigned to each CPU core, // which, just like the Flexible pool, will only run when there is something // in the queue. });
