How do you ensure at-least-once delivery?
To ensure at-least-once delivery in GCP, especially with Cloud Pub/Sub, you must design your system to acknowledge messages only after successful processing. In Cloud Pub/Sub, messages are delivered at least once by default, meaning duplicates can occur. Here's how to ensure at-least-once delivery reliably:
Acknowledge after processing: Don’t acknowledge the message immediately upon receipt. Acknowledge it only after the message is successfully processed and persisted.
Implement retries: If processing fails or crashes before acknowledgment, Pub/Sub will re-deliver the message after the acknowledgment deadline expires.
Use Dead Letter Topics: For messages that consistently fail, dead letter topics help isolate them for later review, avoiding endless retries.
Idempotency: Make your message processing logic idempotent so that reprocessing the same message doesn't lead to inconsistent results.
Monitoring & Alerts: Use Cloud Monitoring to track undelivered or retried messages.
This guarantees messages won’t be lost, even if duplicates must be handled.
