SAGA Pattern:?

Short answer: Break a long-running transaction into smaller steps, where each step is a local transaction managed by a single microservice. Use compensation actions for each step to ensure consistency.

Real-world example (ShopNest)

After payment succeeds, ShopNest publishes OrderPaid. Inventory and Notification services react independently—no giant distributed transaction.
