Kafka is a distributed Message System Based on publishing and subscription. It has the following features. 1. Provides message persistence and access performance for a constant time. 2. high throughput. A cheap commercial machine can transmit up to messages per second. 3. Supports message partitions, distributed consumption, and ordered messages in the Kafka server. 4. Supports horizontal scaling. 5. Suppor

I. Some concepts and understandings about Kafka Kafka is a distributed data flow platform that provides high-performance messaging system functionality based on a unique log file format. It can also be used for large data stream pipelines. Kafka maintains a directory-based message feed, called Topic. The project called the release of the message to topic was a

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

Kafka does not provide a high availablity mechanism in previous versions of 0.8, and when one or more broker outages, all partition on the outage cannot continue to provide services. If the broker can never be restored, or if a disk fails, the data on it will be lost. And Kafka's design goal is to provide data persistence, at the same time for the distributed system, especially when the cluster size rise to a certain extent, one or more machines down
