Amazon RDS and Aurora zero-ETL integrations vs Mirroring in Microsoft Fabric
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.
Side-by-side comparison
| Aspect | Amazon Web Services | Microsoft Azure |
|---|---|---|
| Service | Amazon RDS and Aurora zero-ETL integrations | Mirroring in Microsoft Fabric |
| 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. | Managed, near-real-time replication of databases (Azure SQL, Cosmos DB, PostgreSQL, Snowflake, and others) into OneLake as Delta tables, with a SQL analytics endpoint. |
| Pricing model | No charge for the integration itself. You pay for change processing on the source and for Redshift compute and storage. | Mirroring compute for replication is free, with free OneLake storage up to a limit tied to capacity size. Queries use Fabric capacity. |

Key differences
- Target. Zero-ETL lands data in Redshift (or a SageMaker lakehouse) for querying. Fabric mirroring lands open Delta tables in OneLake, readable by every Fabric engine and by other Delta readers.
- Sources. Zero-ETL covers Aurora MySQL and PostgreSQL, RDS for MySQL and PostgreSQL, DynamoDB, and others (check the current list). Mirroring covers Azure SQL, Cosmos DB, Azure Database for PostgreSQL, Snowflake, and others, including open mirroring for partners.
