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

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 is only a small bond. It is often used for sending and transferring data. In the official case of Kafka, there is no relevant implementation version of PHP in fact. Now the online circulating Kafka of the relevant PHP library, are some of the programming enthusiasts write their own class library, so there will certainly not be too unified interface standard
