How to Architect Real-Time Replication with Mirrored Azure SQL Databases
Why this matters: Mirrored Azure SQL databases offer a low-latency path to bring transactional data into OneLake without writing custom ETL pipelines. Understanding the underlying replication mechanics is essential to avoid unexpected data staleness or capacity bottlenecks in production environments. In a traditional ETL-heavy architecture, moving data from Azure SQL Database to an analytics…
Real-time data replication to Azure SQL databases is crucial for modern analytics workflows. Mirrored Azure SQL databases offer a streamlined approach, eliminating the need for custom ETL pipelines. This architecture brings transactional data into OneLake with low latency, enhancing real-time analytics capabilities. Key steps include enabling the mirroring connection in the Fabric portal, selecting objects for replication, monitoring initial load and latency, and accessing data via Direct Lake storage in Power BI.
Important considerations involve checking supported data types, monitoring source performance, handling schema changes, and managing capacity throttling. By leveraging these mirrored databases, organizations can achieve a zero-ETL analytics environment, enhancing performance and reducing operational complexity.
