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

1. OverviewAfter one months of observation, business in the integration of Kafka, all aspects are still stable, here is going to take time to share some of the Kafka in the actual scene of some of the use of experience. This blog intends to first to everyone into a door, so that we have a preliminary understanding of Kafka, know what

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

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

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

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. This article will analyze t

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. 1.
