Fast 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
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.

$ 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
