Installing Redis

Installing PHPRedis

phpredis extension is necessary to be installed in your server.
Otherwise composer will alert you.

Installing RSQueue

You have to add require line into you composer.json file

Then you have to use composer to update your project dependencies

And register the bundle in your appkernel.php file

Configuration

In this first version, all conections are localhost:6379, but as soon as posible connections will be configurable.
You need to configure all queues and serializer.
By default serializer has the value 'Json', but also 'PHP' value can be used. Also custom serializer can be implemented by extending default serializer interface. Then you need to add namespace of class into the rs_queue.serializer parameter.

Producers/Consumers

Producer/consumer model allows you to produce elements into one/many queues by using default rsqueue producer service.
One element is pushed into one queue so one and only one consumer will pop and treat this element.

Then you should extend ConsumerCommand so that in this way you can define which queues listen, and in each case, which action execute.

Publishers/Subscribers

This model allows data broadcasting. This means that one or more Subscribers will treat all elements of the queue, but only if they are listening just in the moment publisher publish them.

And, as consumers, subscribers must define which channels they want to listen

By extending PSubscriberCommand you can define patterns instead of queue names.

Events

Custom events are used in this bundle.
