What's Kafka? Kafka, originally developed by LinkedIn, is a distributed, partitioned, multiple-copy, multiple-subscriber, zookeeper-coordinated distributed logging system (also known as an MQ system), commonly used for Web/nginx logs, access logs, messaging services, and so on, LinkedIn contributed to the Apache Foundation in 2010 and became the top open source project. 1.

Kafka usage scenarios are still relatively large, such as buffer queues between asynchronous systems, and in many scenarios we will design as follo

Kafka Connector and Debezium 1. Introduce Kafka Connector is a connector that connects Kafka clusters and other databases, clusters, and other systems. Kafka Connector can be connected to a variety of system types and Kafka, the main tasks include reading from

existing applications or data systems. For example, connect to a relational database. In Kafka, the communication between the client and the server is simple, high-performance, and based on the TCP protocol.
