SQL Server 2019 Big Data Clusters CU20 release notes

Applies to: SQL Server 2019 (15.x)

The following release notes apply to SQL Server 2019 Big Data Clusters cumulative update 20 (CU20).

CU20 changes and new capabilities

Warning

On Cumulative Update 15, the upgrade order is critical. Upgrade your big data cluster to CU15 before upgrading the Kubernetes cluster to version 1.21. If the Kubernetes cluster is upgraded to version 1.21 before BDC is upgraded to CU14 or CU15 then the cluster will end up in error state and the BDC upgrade will not succeed. In this case, reverting back to Kubernetes version 1.20 will fix the problem.
This doesn't affect new deployments of SQL Server 2019 Big Data Clusters CU15 on Kubernetes API 1.21 clusters.

For detailed SQL Server engine changes, check the official SQL Server 2019 CU20 knowledge base article KB 5024276.

Tested configurations for CU20

SQL Server Big Data Clusters CU20 was tested on the following environment combinations:

Container OS Kubernetes API Runtime Data Storage Log Storage
Ubuntu 20.04 LTS 1.23.1 containerd 1.4.6
