Java Microservices: CQRS & Event Sourcing with Kafka

🌟 Java Microservices: Mastering CQRS & Event Sourcing with Kafka 🌟

Your Journey to Mastering Java Microservices

Welcome to the comprehensive course where you will master the art of building robust and scalable microservices using the powerful principles of CQRS (Command Query Responsibility Segregation) and Event Sourcing. Leveraging the expertise of Spring Boot and Apache Kafka, this course will empower you with hands-on experience in crafting your own CQRS & Event Sourcing framework from scratch in Java. 🛠️✨

What You Will Learn:

• Comprehensive Understanding: Dive deep into the concepts of CQRS and Event Sourcing, and learn how they can be applied to create microservices that are decoupled and highly scalable.

• Code from Scratch: Instead of relying on existing frameworks, you'll write every line of code necessary to build your own CQRS & Event Sourcing infrastructure. This will solidify your understanding and mastery over the concepts.

Step-by-Step Guidance:

• Handling Commands & Events: Learn how to handle commands effectively, and understand the importance of events in maintaining the state of your application.

• Mediator Pattern: Implement command and query dispatchers using the mediator pattern to ensure a clean architecture.

• Event Storage with MongoDB: Create an event store/write database in MongoDB, understanding how to record all changes as a sequence of events.

• Read Model with MySQL: Establish a read database in MySQL, and learn the nuances of creating and changing aggregate state using event messages.

• Event Versioning & Concurrency Control: Apply event versioning and implement optimistic concurrency control to maintain data integrity and consistency.

• Integration with Apache Kafka: Produce events to and consume events from Apache Kafka, essential for handling real-time data streams.

• Replay Event Store: Learn how to replay the event store to recreate the state of an aggregate, and understand how this can be used for testing and debugging.

• Separation of Concerns: Separate read and write concerns effectively, ensuring each aspect of your microservice is optimized for its role.

• Domain-Driven Design Best Practices: Structure your code using DDD best practices to ensure a clear domain model and well-organized system.

• Versatile Replaying: Not only will you replay the event store to recreate the read database, but you'll also learn how to do this into a different database type – PostgreSQL.

Course Highlights:

• Real-World Application: This course is designed to provide you with real-world scenarios where you can apply CQRS and Event Sourcing principles.

• Full Code Coverage: From command handling to event replay, you'll write the full spectrum of code required for a functional CQRS & Event Sourcing microservice.

• Scalability & Decoupling: Learn how to create microservices that are not only scalable but also decoupled, ensuring robust and maintainable code.

Your Expertise by the End:

By completing this course, you will have a deep understanding of CQRS and Event Sourcing within the context of Java microservices and Apache Kafka. You'll be able to architect systems that are not only clean and modular but also highly performant and scalable. 🚀
