Preface
Distributed is one of the necessary skills for programmers. It belongs to the necessary category in the interview process, and it is often used in work. Kafka is a distributed publish-subscribe-based message queue. At present, its charm is endless. For the mystery of Kafka, we still need to explore in detail.
To talk about how familiar with Kafka, I believe that Ali’s bigwigs have the most say, so the content shared today is the "limited notes" provided by Alibaba. All the essence of Kafka is written here. Exclamation: As expected of Alibaba's technical officer, I really took it!
Regarding this limited Kafka note, I can only show part of the chapter content and core screenshots in the article. If you need a complete pdf, just add the VX below!

to sum up
We always like to pay tribute to the great gods of big factories, but in fact, great gods are no more than mortals. Compared with rookie programmers, they spend a little more thought. If you don't work hard, the gap will only grow bigger and bigger. In fact, as a programmer, it is necessary to enrich one's knowledge reserve and enhance the depth and breadth of one's knowledge. In my opinion, the rewards will be as much as you pay.
Learning Kafka is not as difficult as imagined. The content in this limited Kafka note will inspire and help you to learn Kafka. If you need this full version of Kafka notes , you just need to support me in this article.
