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
