The space available property is not computed correctly

The Database.SpaceAvailable property is not computed correctly. The reason for this issue is that the input used in the calculation of this property, as seen in the source code, relies on a join operation between the sys.allocation_units and sys.partitions DMVs. However, this inner join is incompatible with columnstore indexes, as clearly documented in the official documentation. Consequently, the size is inaccurately computed for databases using columnstores. The solution is straightforward: remove this incompatible join operation from the calculation.

Inizia in src/Microsoft/SqlServer/Management/SqlEnum/PostProcessDatabaseInsideAttribs.cs, nel calcolo collegato di Database.SpaceAvailable. Esamina come vengono unite sys.allocation_units e sys.partitions, quindi verifica il risultato per un database che usa indici columnstore. Il lavoro è completato quando la proprietà riporta lo spazio disponibile corretto senza l'unione incompatibile.
