Overview

Saga Pattern manages distributed transactions across microservices using a sequence of local transactions. Each step publishes events or commands, with compensating transactions for rollback.

<aside> ℹ️ Why It Matters: Understanding Saga Pattern is essential for building robust, scalable, and secure modern applications.
