Usage

The following snippet instantiate a bus with a Kafka transport.

The Kafka stream is divided between 16 (0 to F) partitions based on the hash of the event hash.

<?php

use Aerogram\EventBus\EventBus\SimpleBus;
use Aerogram\EventBus\Kafka\KafkaTransport;
use Aerogram\EventBus\Kafka\Middleware\KafkaPartitioner;

$bus = new SimpleBus(
        new KafkaTransport,
        [
            new KafkaPartitioner(function($event, $options) {
                $hash = md5($event);

                return hexdec($hash{0});
            })
        ]
    );

// The following event will be published in partition 15
$bus->publish('event.test', '{"name": "test", "payload": "This is a test..."}');
