#### Installation

1. Install [librdkafka c library](https://github.com/edenhill/librdkafka)

```bash
$ cd /tmp
$ mkdir librdkafka
$ cd librdkafka
$ git clone https://github.com/edenhill/librdkafka.git .
$ ./configure
$ make
$ make install
```
2. Install the [php-rdkafka](https://github.com/arnaud-lb/php-rdkafka) PECL extension

```bash
$ pecl install rdkafka
```

3. a. Add the following to your php.ini file to enable the php-rdkafka extension
`extension=rdkafka.so`

b. Check if rdkafka is installed
__Note:__ If you want to run this on php-fpm restart your php-fpm first.

php -i | grep rdkafka

Your output should look something like this

rdkafka
rdkafka support => enabled
librdkafka version (runtime) => 1.0.0-RC2
librdkafka version (build) => 0.11.4.0


4. Install this package via composer using:

composer require rapide/laravel-queue-kafka

5. Add LaravelQueueKafkaServiceProvider to `providers` array in `config/app.php`:

Rapide\LaravelQueueKafka\LaravelQueueKafkaServiceProvider::class,

If you are using Lumen, put this in `bootstrap/app.php`

$app->register(Rapide\LaravelQueueKafka\LumenQueueKafkaServiceProvider::class);

6. Add these properties to `.env` with proper values:

QUEUE_DRIVER=kafka

7. If you want to run a worker for a specific consumer group

export KAFKA_CONSUMER_GROUP_ID="group2" && php artisan queue:work --sleep=3 --tries=3

Explaination of consumergroups can be found in this article
http://blog.cloudera.com/blog/2018/05/scalability-of-kafka-messaging-using-consumer-groups/

#### Usage

Once you completed the configuration you can use Laravel Queue API. If you used other queue drivers you do not need to change anything else. If you do not know how to use Queue API, please refer to the official Laravel documentation: http://laravel.com/docs/queues

#### Testing

Run the tests with:

``` bash
vendor/bin/phpunit
```

#### Acknowledgement

This library is inspired by [laravel-queue-rabbitmq](https://github.com/vyuldashev/laravel-queue-rabbitmq) by vyuldashev.
And the Kafka implementations by [Superbalist](https://github.com/Superbalist/php-pubsub-kafka) be sure to check those out.
