Mirroring in Fabric

A Fabric feature that continuously replicates operational databases (Azure SQL, Cosmos DB, Snowflake and others) into OneLake as Delta tables in near real time.

Definition

Mirroring uses CDC to keep a read-only replica in OneLake that can be queried through a SQL analytics endpoint and Direct Lake without building ETL.

Exam tip

Near-real-time replica of an operational database with no ETL = mirroring; in-place reference of files = shortcut.
