Overview
Kafka is a distributed publish-subscribe messaging system, which is simply a message queue, and the benefit is that the data is persisted to disk (the focus of this article is not to introduce Kafka, not much to say).
Author: Wang, JoshI. Basic overview of Kafka1. What is Kafka?The definition of Kafka on the Kafka website is called: adistributed publish-subscribe messaging System. Publish-subscribe is the meaning of publishing and subscribing, so it is accurate to say that Kafka is a message subscription and release system. Initiall
This was a common question asked by many Kafka users. The goal of this post are to explain a few important determining factors and provide a few simple formulas.More partitions leads to higher throughputThe first thing to understand are that a topic partition are the unit of parallelism in Kafka. On both the producer and the broker side, writes to different partitions can be do fully in parallel. So expensi
Originally a distributed messaging system developed by LinkedIn, Kafka became part of Apache, which is written in Scala and is widely used for horizontal scaling and high throughput. At present, more and more open source distributed processing systems such as Cloudera, Apache Storm, spark support and Kafka integration. 1 overview

The Publish/Subscribe feature makes the coupling between sender and receiver looser, the sender does not have to care about the destination address of the receiver, and the receiver does not have to care about the sending address of the message, but simply sends and receives the message based on the subject of the message.
