Kafka is a distributed, partitioned, and reproducible message system. It provides common messaging system functions, but has its own unique design. What is this unique design?
First, let's look at several basic terms of the message system:

Spring Cloud is an ordered collection of frames. The development of the spring boot model simplifies the development of a distributed system infrastructure, and can be started and deployed in a one-click fashion with spring boot development. Spring Cloud combines today's more mature, proven service framework with the spring boot style for re-encapsulation, masking complex configuration and implementation pr

1. Version introduction:
Currently we are using a version of kafka_2.9.2-0.8.1 (scala-2.9.2 is officially recommended for Kafka, in addition to 2.8.2 and 2.10.2 available)
2. Environment preparation:
Install JDK 6. The current version is 1.6 and java_home is configured.

Apache Kafka is a distributed streaming platform. What exactly does that mean?We think of the three key capabilities of the streaming platform:1. Let you publish a subscription to the data stream. So he's a lot like a message queue and an enterprise-class messaging system.2. Lets you store data streams in a high-fault-tolerant manner.3. Let your data flow out of the current processing them.What is Kafka goo
