Introduction into Kafka in Production – Part 1

Introduction

Does anyone know what kafkasque is? I didn’t until I started working with Apache Kafka and discovered its nightmarish complexity 🙂 As with any technology, gaining knowledge makes complexity go away or at least complexity becomes less nightmarish. 

In this (very) opinionated introduction we are going to dive into a few important aspects of Kafka. In addition, we’ll deploy basic Kafka demo using Docker. Of course, this post doesn’t replace existing great courses, books and official documentation. 

Though, it gives you a basic understanding of what Kafka is and how it works.
