kafka introduction

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
