Online Courses Udemy - Apache Kafka for Developers using Spring Boot[LatestEdition], Learn to build enterprise standard Kafka producers/consumers with Kafka Unit/Integration tests using Spring Boot.
This course is structured to give you a theoretical and coding experience with Apache Kafka using SpringBoot. This course is targeted for developers who would like to build enterprise standard Kafka Client applications using SpringBoot.
If you are looking forward to learning the below-listed things:
Use cases where Kafka fits really well
Internals of Kafka and how it works
Built Enterprise Standard Kafka Client Applications using Producer/Consumer API using Spring Boot
Unit/Integration Tests for the Kafka Client Applications
Then this is the right course for you. This is a pure hands-on oriented course where you will be learning the concepts through code.
By the end of this course, you will have a complete understanding of coding and implementing Kafka Clients using SpringBoot with Producer/Consumer API.
