Kafka is a highly huff and puff distributed subscription message system, which can replace the traditional message queue for decoupled data processing, cache unhandled messages, and has higher throughput, support partition, multiple replicas and redundancy, so it is widely used in large-scale message data processing applications. Kafka supports Java and a variety of other language clients and can be used in
main principles and ideas of optimization
Kafka is a highly-throughput distributed messaging system and provides persistence. Its high performance has two important features: the use of disk continuous read and write performance is much higher than the characteristics of random reading and writing, concurrency, a topic split into multiple partition.
To give full play to the performance of Kafka, these two

A very important design principle of distributed systems is loose coupling, that is, minimizing dependencies between subsystems. In this way, subsystems can evolve, maintain, and reuse independently of each other. Message Queue (MQ) is a good means of decoupling. For more information about the role of MQ in system integration, see the enterprise integration patterns (EIP) book or corresponding website. Simply put, the publisher only publishes a message to MQ, and no matter who gets it, the messa

Preface
Kafka is a distributed, multi-partition, multi-replica messaging service. With Message Queuing, producers and consumers interact asynchronously without having to wait for each other. Compared to traditional messaging services, Kafka has the following features:Themes can be scaled horizontally by partitioning (Partition).Partitions are distributed across multiple nodes to achieve high data availabili

High throughput of Kafka
As the most popular open-source message system, kafka is widely used in data buffering, asynchronous communication, collection logs, and system decoupling. Compared with other common message systems such as RocketMQ, Kafka ensures most of the functions and features while providing superb read/write performance.

What is Kafka?
Kafka, originally developed by LinkedIn, is a distributed, partitioned, multi-replica, multi-subscriber, zookeeper-coordinated distributed log system (also known as an MQ system) that can be used for Web/nginx logs, access logs, messaging services, etc. LinkedIn contributed to the Apache Foundation and became the top open source project in 2010.

Zookeeper uses zookeeper-3.4.7.tar.gz and kafka_2.10-0.9.0.0.tgz. First, install JDK (jdk-7u9-linux-i586.tar.gz) and SSH. The IP addresses are allocated to kafka1 (192.168.56.136), kafka2 (192.168.56.137), and kafka3 (192.168.56.138 ). The following describes how to install SSH and how to build and use zookeeper and Kafka clusters.
