Link to Fabric - Cost

Hi Luigia-Costabil, 

That depends oon how much data you have. 

The Link to Fabric feature will take all your dataverse data, and create parquet files for it that are compatible with Fabric Lakehouses. These parquet files are stored in Dataverse, not in OneLake. 

So if you have a very small dataverse enviornment, the storage will be small. If you have a very large one, the storage used will be larger.
