Apache Kafka is publish-subscribe messaging rethought as a 
distributed commit log.

Fast
    A single Kafka broker can handle hundreds of megabytes 
    of reads and writes per second from thousands of clients.

Scalable
    Kafka is designed to allow a single cluster to serve as 
    the central data backbone for a large organization. It 
    can be elastically and transparently expanded without 
    downtime. Data streams are partitioned and spread over a 
    cluster of machines to allow data streams larger than the 
    capability of any single machine and to allow clusters of 
    co-ordinated consumers

Durable
    Messages are persisted on disk and replicated within the 
    cluster to prevent data loss. Each broker can handle 
    terabytes of messages without performance impact.

Distributed by Design
    Kafka has a modern cluster-centric design that offers 
    strong durability and fault-tolerance guarantees. 


Groupname and username

You must have the 'kafka' group and user to run this script,
for example:

  groupadd -g 323 kafka
  useradd -u 323 -g 323 -c "Apache Kafka user" -d /var/lib/kafka \
    -s /bin/sh kafka
