In this blog post, I’ll walk you through how to create a Kafka Streams application in an idiomatic Clojure style. I won’t assume any knowledge of Kafka or Kafka Streams, but if you’ve never heard of them before this post may be a bit overwhelming - I’d check out Confluent’s introduction to Kafka Streams, and also the Kafka Streams docs. Kafka can be thought of as a persistent, highly scalable, distributed message queue.
First off, welcome to my brand new blog. I’m a Clojure programmer by day, so this blog will focus pretty much entirely on Clojure (as you probably guessed from the name). My main aim with this blog is to document step-by-step solutions for any difficult, or rare, problems I come across. I was inspired to start the blog by a post on Medium. The post talks about how Clojure can be hard for beginners, due to the lack of step-by-step guides for common problems.
