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

    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/
