Improve Size and Metadata Visibility for Tables in Microsoft Fabric Data Warehouse

There is currently no reliable way to view the size of a data warehouse in Microsoft Fabric using T-SQL or the Fabric Explorer. This makes it difficult to manage storage, troubleshoot performance issues, and understand data usage.

 

Recommended improvements:

  • Fix existing DMVs so they return accurate storage usage and metadata for Fabric Data Warehouses.

  • Update the Fabric Explorer Table Properties UI (specifically the Properties tab) to show:

    • Current Size – the size of active data (such as optimized Delta files)

    • Total Size – the size of all files, including older versions and unoptimized data

    • V-Order Status – to provide insight into data layout optimization

    • Last Compaction Timestamp

    • Per-file Metrics – such as file sizes, modification times, and row counts

  • Enhance the Fabric Explorer column list to indicate whether a column has a primary key, foreign key, or unique index defined.

These changes would significantly improve visibility into storage and performance, making it easier to manage and optimize Fabric Data Warehouses.

Note: While some of this information can be obtained via OneLake Explorer or a Spark notebook, the experience is currently cumbersome and not user-friendly.  🍍🍕
