README

A symfony messenger transport implementation for redis streams.

NOTE: Most of the logic has moved to the Core Symfony Messenger component in 4.3. So this bundle is not longer a requirement to use messenger with redis streams. You can now use the redis:// instead of redis-stream:// and remove this bundle from your requirements.

Requirements

• PHP: ^7.1
  • Redis Extension: ^4.2
• Redis Server: ^5.0

Symfony compatibility

When upgrading to symfony 4.3 you should replace this bundle with the symfony redis:// transport and remove the bundle from your requirements.

Installation

You need composer to install this bundle to your symfony application.

composer require handcraftedinthealps/redis-transport-bundle

Configuration

Symfony

When using the symfony/framework-bundle you can configure the following:

# config/packages/framework.yaml
framework:
    messenger:
        routing:
            'HandcraftedInTheAlps\Bundle\RedisTransportBundle\Message\DomainEventMessage':
                senders: ['redis_stream']
        transports:
            redis_stream: 'redis-stream://127.0.0.1:6379/my_stream/my_group/my_consumer'

You can then send a DomainEventMessage or your custom Message over the redis stream:

use HandcraftedInTheAlps\Bundle\RedisTransportBundle\Message\DomainEventMessage;

$this->messageBus->dispatch(
    new DomainEventMessage(
        'mountain.modified',    // the custom event action
        'mountain',             // the model which has been changed
        '1',                    // the model id or uuid
        [                       // the model payload
            'id' => '1',
            'name' => 'Piz Buin',
            'height' => 3312,
        ]
    )
);

And you can consume the messages with:

bin/console messenger:consume-messages redis_stream

Have also a look at the messenger component documentation and messenger usage documentation.

Commands

Messages in streams won't be removed by default. Therefor this bundle provides a command:

bin/console redis-transport:trim <redis-dsn> --maxlen 1000
