Amazon RDS and Aurora zero-ETL integrations vs Datastream
RDS and Aurora zero-ETL integrations map partly to Datastream replication into BigQuery, or to BigQuery federated queries against Cloud SQL.
AlloyDB's columnar engine handles analytics in place.
Side-by-side comparison
| Aspect | Amazon Web Services | Google Cloud |
|---|---|---|
| Service | Amazon RDS and Aurora zero-ETL integrations | Datastream |
| Lifecycle | Generally available | Generally available |
| What it is | Managed, near-real-time replication of operational database data into Amazon Redshift or a SageMaker lakehouse, with no pipelines to build. | Serverless change data capture and replication from operational databases into BigQuery, Cloud Storage, and other targets. |
| Pricing model | No charge for the integration itself. You pay for change processing on the source and for Redshift compute and storage. | Datastream is billed per GiB processed, plus BigQuery storage and queries. |

Key differences
- Datastream is a CDC pipeline you configure, not a single checkbox integration.
- Federated queries read live data without copying it.

FAQ
What is the Google Cloud equivalent of Amazon RDS and Aurora zero-ETL integrations?
RDS and Aurora zero-ETL integrations map partly to Datastream replication into BigQuery, or to BigQuery federated queries against Cloud SQL. AlloyDB's columnar engine handles analytics in place.
How does pricing compare between Amazon RDS and Aurora zero-ETL integrations and Datastream?
AWS: No charge for the integration itself. You pay for change processing on the source and for Redshift compute and storage. Google Cloud: Datastream is billed per GiB processed, plus BigQuery storage and queries. Check the official pricing pages for current rates.
What is the Azure equivalent?
Mirroring in Microsoft Fabric (partial match). Aurora and RDS zero-ETL integrations (to Amazon Redshift or a SageMaker lakehouse) map to Microsoft Fabric mirroring, which continuously replicates Azure SQL, Cosmos DB, PostgreSQL, and other sources into OneLake as Delta tables.
