Microsoft announce that SQL Server 2019 is generally available. There are the usual product enhancements you’d expect with, from a licensing perspective, the most significant being support for deploying Big Data Clusters. A new SA benefit gives customers an allowance for licensing Big Data Cluster nodes, with additional licences available in the (inevitable) 2-core pack. There are also SA benefits added for licensing Disaster Recovery solutions.
