The latest SQL Server 2022 RC indicates the final commercial version will soon become solidified & available with new Azure cloud functionality built-in

SQL Server 2022 Release Candidate 0 Now Available — Redmondmag.com

Microsoft last week announced the release of SQL Server 2022 Release Candidate (RC) 0.   The RC 0 designation is old Microsoft phraseology. It used to mean that the software bits were feature complete and ready for imaging on hardware by Microsoft’s partners. Possibly, it now just now means that the product is close to commercial release (“general availability”).

In any case, the free-trial release of SQL Server 2022 RC 0 can be downloaded at this page. It’s good for 180 days. SQL Server 2022 RC 0 also can be tried by running an Azure Virtual Machines image of it, which is available from the Azure Marketplace.   RC 0 is bringing a Degree of Parallelism Feedback capability to the Query Store, which is a feature that captures query history and run-time statistics. The Degree of Parallelism Feedback capability is designed to reduce “inefficient parallelism” across repeated queries, per Microsoft’s “What’s New” document description.
