Niko Neugebauer continues a series on columnstore indexes:
In this post we are going to test one of the more promising technologies in SQL Server-based offerings – Vector data types and its relationship with the Columnstore Indexes. The tests I am running right now are executed against SQL Server 2025 RTM, the latest and greatest SQL Server version available to customers. Given that some parts of the SQL Server 2025 were delivered as a Preview Features, the current situation might change in the future for SQL Server 2025 (at least, Half-precision float support should evolve into the fully supported feature, in my opinion). At very least, I do expect reasonably fast evolution of the space on Azure SQL Database & Azure SQL Managed Instance.
This seems like more pain than joy, which is the unfortunate reality of v1 features in SQL Server anymore.
