Before we introduce why we use Kafka, it is necessary to understand what Kafka is. 1. What is Kafka.
Kafka, a distributed messaging system developed by LinkedIn, is written in Scala and is widely used for horizontal scaling and high throughput rates. At present, more and more open-source distributed processing systems
Kafka is a distributed MQ system developed by LinkedIn and open source, and is now an Apache incubation project. On its homepage describes Kafka as a high-throughput distributed (capable of spreading messages across different nodes) MQ. In this blog post, the author simply mentions the reasons for developing Kafka without choosing an existing MQ system. Two reaso
Kafka's cluster configuration generally has three ways , namely
(1) Single node–single broker cluster;
(2) Single node–multiple broker cluster;(3) Multiple node–multiple broker cluster.
The first two methods of the official network configuration process ((1) (2) Configure the party Judges Network Tutorial), the following will be a brief introduction to the first two methods, the main introduction of the last method.

Kafka is a high-throughput distributed publish-subscribe messaging system that has the following features:
Provides persistence of messages through the disk data structure of O (1), a structure that maintains long-lasting performance even with terabytes of message storage. High throughput: Even very common hardware Kafka can support hundreds of thousands of messages per second. Support for partitioning mess
