Introduction to Kafka

Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.

Terminology:

• Producers send messages to brokers
• Consumers read messages from brokers
• Messages are sent to a topic

# To Setup and build Kafka:
$ git clone git@github.com:apache/kafka.git
$ cd kafka
$ git checkout -b 0.8 remotes/origin/0.8
$ ./gradlew jarAll


# Start Zookeeper
$ bin/zookeeper-server-start.sh config/zookeeper.properties
