A Gentle Introduction to Kafka Consumer Group

You may have heard about Kafka if you are studying for a system design interview or dealing with data-intensive applications. Even if you don’t work with distributed systems before, you probably have heard of “Kafka” during a water cooler chat with your colleagues. In the system design interview, Kafka was a magic box that solved all reliability and scalability issues. In the industry, Kafka was trusted by Fortune 100 companies to be the backbone of their scalable infrastructure. I got to work on Kafka for the past six months, trying to scale our event-driven notification pipeline. I realized many terminologies differ from AWS Kinesis, GCP Pubsub, and Kafka. However, Kafka is a versatile tool that all software engineers should consider when scaling their systems to millions of users. In this article, I am giving you a quick introduction to Kafka, specifically on what is a Consumer group, because it is a new and fresh perspective coming from someone who knows AWS Kinesis. This article can be a very brief introduction to the Kafka component. Still, I will dive deep into the Consumer group and give you some examples of how the Consumer group fits into a system case study. <a href="https://levelup.gitconnected.com/a-gentle-introduction-to-kafka-consumer-group-530d3a3286dd">Click Here</a>
