Description
This course is for all things Kafka, Java, Spring and Spring Boot!
This course will take you as a developer who knows just the basics on Spring Boot and Java to being able to develop a fully functional, fully tested, application that connects with the Kafka messaging broker in order to send and receive messages.
In fact with our comprehensive code walkthroughs that start from scratch in writing our Spring Boot application you would be able to put together the application with no previous Spring Boot experience!
This course has been developed by a team of highly experienced Java Software Engineers and Kafka consultants working closely with John Thompson, the Spring Framework Guru - we understand what a developer needs from such a course - it has been designed with the Java developer in mind to be able to gain the most from it.
All the code that we walk through is available in the included git repositories for you to use as a starting point for your work, or for you to fork and extend as you begin to explore Kafka further. Along the way there are assignments enabling you to put in practice what you have been learning, to build out a fully rounded microservices architecture. We have accompanying articles on many of the Kafka concepts covered in the course - these go into greater depth providing you the opportunity to continue your learning and gain an advanced understanding on these areas.
Inside this course you will learn about:
Kafka Background and Concepts:
The Kafka messaging broker
All the key Kafka concepts including messages, keys, topics, partitions and offsets
