12.46Duplicate event scenario

Kafka/queue delivers the same customer event twice.

Answer:

“That's normal under at-least-once delivery. If the event maps to an idempotent Salesforce upsert, duplicate execution may already be harmless. If there are non-idempotent side effects, I'd use event-level deduplication or downstream-native idempotency keys.”
