This is a sample project to demo saga pattern.
Consider the real world example for transactions across distributed systems. When user process orders, order-service needs manage inventory, and handle payments. We need a solution that ensures data consistency and reliability, even in the face of failures or network issues. That's where the Saga Pattern comes in.
