A single Kafka broker can handle hundreds of megabytes of reads and writes per
second from thousands of clients.
Currently deploys Apache Kafka 2.9.2-0.8.2.1
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

cluster of machines to allow data streams larger than the capability of any
single machine and to allow clusters of co-ordinated consumers
Messages are persisted on disk and replicated within the cluster to prevent
data loss. Each broker can handle terabytes of messages without performance
Distributed by Design
Kafka has a modern cluster-centric design that offers strong durability and

$ juju deploy zookeeper $ juju deploy kafka $ juju add-relation kafka zookeeper
First we need to get a hold of the zookeeper servers that are kafka brokers
are connected to:
$ juju run --unit=kafka/0 ./hooks/utils.py 10.0.3.221:2181
We can list all the cli commands available to us via
$ juju run --unit=kafka/0 "ls bin"
kafka-console-consumer.sh kafka-console-producer.sh kafka-consumer-perf-test.sh kafka-preferred-replica-election.sh kafka-producer-perf-test.sh kafka-reassign-partitions.sh kafka-replay-log-producer.sh kafka-simple-consumer-perf-test.sh kafka-simple-consumer-shell.sh kafka-topics.sh
We can create a topic with
$ juju run --unit=kafka/0 "./bin/kafka-topics.sh --zookeeper 10.0.3.221:2181 --create --topic my_topic_name --partitions 5 --replication-factor 1"
We can list topics with
$ juju run --unit=kafka/0 "./bin/kafka-topics.sh --zookeeper 10.0.3.221:2181 --list
