Almost lost in all the announcements from Ignite was a bunch of amazing new features that were added to the Provisioned Resources/SQL Pool section (read SQLDW functionalities) side of Azure Synapse Analytics (formally called Azure SQL Data Warehouse).
One of the more interesting options is ordered clustered columnstore indexes. That seems like something which would be nice to have on-prem. The segment elimination works on-prem today, but ordering is accidental at best. By that, I mean the way that SQL Server loads data into a CCI—roughly, in the order in which you insert it—is not guaranteed to work that way and could change in the future.
