Brief introduction
Kafka is a high-throughput distributed publishing and subscription messaging system
Kafka role must be known
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.

Background:Various Application Systems in today's society, such as business, social networking, search, and browsing, constantly produce information like information factories. In The Big Data era, we are faced with the following challenges:
How to collect this huge information
How to analyze it
How to implement the above two points in a timely manner
These challenges form a business demand model, that is, information about producer production (produce) and consumer consumption (consume) (pr
