Azure SQL Mirror - Recommendation?

We have an Azure SQL Database that contains a large portion of our data.

 

I've been able to successfully set up a mirror of the database in a workspace.

 

I'm fairly new to Fabric and not sure how to proceed given that the data needs some transformation before it can be used in Power BI.

 

These are the two options I'm thinking of but there may be a another option that is better.

 

Option 1

Create views inside the Mirror SQL endpoint where we can filter the data and add some columns that are calculated.  Use these views inside a model.  Not sure of performance using this method.

 

Option 2

Move the data from the mirror to a lakehouse or warehouse and do the transformation along the way.  Have experimented a little with this but the SQL endpoint doesn't seem to show up as a source in a pipeline or Dataflow Gen 2.

 

Any recommendation would be greatly appreciated.

 

Thank you.

@acenter41, Thanks for reaching Fabric community support.

 

  • For straightforward transformations, Dataflows Gen2 offers a user-friendly interface with scheduling capabilities.

  • For efficient processing of large datasets with frequent changes,  Incremental Data Loads with CDC is recommended.

  • For complex transformations requiring advanced scripting, Notebooks provides the necessary flexibility.

Hello @acenter41 


go for hybrid

 

Create views in the mirrored SQL endpoint to handle lightweight transformations like filtering, basic calculations, or aggregations. This minimizes data movement and leverages the existing mirrored database.

 

For more complex transformations (e.g., combining datasets, advanced calculations), move data to a Lakehouse or Warehouse.

Connect Power BI directly to the Lakehouse/Warehouse for reports requiring extensive transformations

For simpler reports, connect Power BI directly to SQL views using DirectQuery mode.

 

Where you mention to move data to a Lakehouse or Warehouse for complex transformations, how would you move the data from the Mirror to the lh/wh?  The mirror does not seem to appear as a source when trying to move data from it using a pipeline or dataflow.

Since Data Pipelines/Dataflows don’t directly support Mirror as a source, use a Fabric Notebook to manually extract and load data.
