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).
on the subject or content. 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.

In addition to supporting RABBITMQ's automated configuration, Spring Cloud bus supports Kafka, which is now widely used. In this article, we will build a Kafka local environment and use it to try the support of Spring Cloud Bus for Kafka to realize the function of message bus.

Kafka is a distributed, partitioned, replicable messaging system. It provides the functionality of a common messaging system, but has its own unique design. What does this unique design look like?
Let's first look at a few basic messaging system terms:
Kafka the message to topic as a unit.• The program that will release the message to Kafka topic
Introduction to Kafka
Kafka is a high-throughput distributed Message Queue with high performance, persistence, multi-copy backup, and horizontal scaling capabilities. It is usually used on big data and stream processing platforms. Message Queues all have the producer/consumer concept. The producer writes messages to the queue, while the consumer obtains messages from the queue. It is generally used for deco
Kafka is a distributed streaming platform, what exactly does it mean.
The streaming platform has the following three main functions:☆ Publish and subscribe stream records, similar to Message Queuing or enterprise-level messaging systems.☆ You store stream records in a fault-tolerant manner.☆ Timely processing when the flow record is generated.
Kafka is used in two major categories of applications:☆ Establis
