Kafka Setup Saga Choreography with Kafka + Spring Boot | Distributed Transactions

In this video, we’ll dive deep into the Saga Pattern (Choreography Implementation) using Spring Boot + Kafka.

Github Repo: https://github.com/eramanmalhi/saga-c...

🔹 We’ll start with understanding the high-level flow of our distributed system.
🔹 Next, we’ll explore the low-level design with a complete code walkthrough.
🔹 Finally, before the demo, I’ll show you how to set up Kafka locally and create the required topics.

👉 If you are new to the Saga Pattern, I recommend watching my previous video for a detailed introduction (linked in the top right corner).

🚀 What’s Covered in this Part:

Multi-module Maven project structure

order-service → handles order creation & status tracking

inventory-service → manages product stock & availability

payment-service → simulates payment processing

common-utils → shared Kafka events & constants

End-to-end flow of the Saga using local transactions:

Order creation → OrderCreated event

Inventory stock check → StockConfirmed / StockUnavailable event

Payment processing → PaymentCompleted / PaymentFailed event

Rollback & compensation logic with Kafka topics

Step-by-step Kafka setup on local machine

Code walkthrough & explanation of event publishing and consumption

By the end of this video, you’ll clearly understand how services communicate asynchronously using Kafka in a Saga Choreography pattern.

⚡ Stay tuned and keep practicing — remember, hands-on coding is the best way to learn!
