SQL Server Big Data Clusters (BDC) is a capability brought to market as part of the SQL Server 2019 release. BDC extends SQL Server’s analytical capabilities beyond in-database processing of transactional and analytical workloads by uniting the SQL engine with Apache Spark and Apache Hadoop to create a single, secure, and unified data platform. BDC is available exclusively to run on Linux containers, orchestrated by Kubernetes, and can be deployed in multiple-cloud providers or on-premises.
Today, we’re announcing the release of the latest cumulative update, CU11, for SQL Server Big Data Clusters, which includes important capabilities:
- Encryption at Rest with external key providers, commonly known as “bring your own key” (BYOK).
- Several SQL Server PolyBase Hadoop fixes and SQL Server PolyBase additional support to many data sources.
Major improvements in this update are highlighted below, along with resources for you to learn more and get started.
Data Encryption at Rest
SQL Server 2019 CU8 introduced the Encryption at Rest initial feature set, bringing together a system-managed experience across both SQL Server and HDFS components. With each additional release shaped by our community and insightful customer feedback, many features were added. With the release of the latest cumulative update, CU11, we get to a complete Encryption at Rest feature set, with seamless application-level encryption for the SQL Server and HDFS components.
In CU11, we introduced the BYOK functionality with integration with external key providers, such as Hardware Security Modules (HSM) or services like Azure Key Vault or even Hashicorp Vault. With that capability SQL Server Big Data Clusters Encryption at Rest feature set now contains both system-managed and user-managed Encryption at Rest for SQL Server and HDFS components.
To learn more about the complete Encryption at Rest feature set, see the in-depth documentation:
