No data appearing at the destination - Amazon Managed Streaming for Apache Kafka

No data appearing at the destination

  • Symptom: The Channel is ACTIVE but no data appears at the destination.

  • Causes: Service-role permission problems (delivery is retried but never succeeds, so nothing is written); no new data produced after enablement (the Channel does not backfill).

  • Resolution: Check Amazon CloudWatch Logs for AccessDenied or permission errors, and verify the service role has the required S3 Tables / S3, Glue Schema Registry, and KMS permissions. Confirm producers are actively writing to the topic (check BytesInPerSec). Remember that only data produced after enablement is delivered.
