# MOTIVATION:  As rails apps are growing, people are noticing the drawbacks
# of the ActiveRecord pattern.  Several apps I have seen, and several
# developers I have spoken to are looking towards other patterns for object
# persistence.  The major drawback with ActiveRecord is that the notion
# of the domain object is conflated with what it means to store/retrieve
# it in any given format (like sql, json, key/value, etc).
#
# This is an attempt to codify the Repository pattern in a way that would
# feel comfortable to beginner and seasoned Ruby developers alike.

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
