(The preferred course for practical learning of Kafka technology. The content of the course is practical throughout the course, without sloppiness, but does not include the teaching of basic knowledge. Students need to have a certain Kafka technical foundation before learning. The course content includes Kafka java Consumer practice, Kafka integration framework, Kafka distributed cluster architecture, Kafka performance testing practice, Kafka cluster monitoring practice, Kafka user behavior portrait, Kafka performance storage optimization, and how to improve Kafka throughput and other enterprise-level technologies.)
