Answer
Change streams resume from a resumeToken or clusterTime, ensuring fault-tolerant event processing with no data loss or duplication.
Quick Answer
Resumable change streams let you restart a change stream after failure from exactly where it left off using a resume token. Save the resume token with each processed event. On restart, pass startAfter: . This guarantees at-least-once processing. Critical for event-driven architectures where missing events would cause data inconsistency downstream.
