Key Features Introduced in SQL Server 2022
Here are some of the key new features introduced in SQL Server 2022:
Cloud-connected features:
- Azure Synapse Link: Integrates operational data in SQL Server with Azure Synapse Analytics, enabling near-real-time analytics and insights and bridging the gap between transactional and analytical workloads.
- Azure Arc-enabled SQL Server: Extends Azure management and services to SQL Server instances running anywhere, including on-premises, multi-cloud, and edge environments, ensuring centralized governance and control.
- Backup and restore to S3-compatible object storage: Provides flexibility and cost savings by enabling direct backups and restores to and from S3-compatible object storage like Dell ECS or PowerScale.
Performance and scalability:
- Segment elimination for string, binary, guid, and datetimeoffset: Improves query performance by selectively scanning only relevant data segments, extending this capability to additional data types.
- XML compression: Optimizes storage for XML data and indexes, reducing space requirements and potentially improving query performance.
- Resumable online index creation: Allows for pausing and resuming index creation operations, minimizing downtime and improving availability.
Security:
- Improved certificate and key management: Supports creating certificates from PFX files, backing up and restoring certificates and keys to Azure Blob storage, and using RSA-3072 as the default for system-generated certificates.
- Azure Purview integration: Enables data discovery, classification, and governance for SQL Server data using Azure Purview, ensuring compliance and data protection.
Machine learning:
- Python support in Machine Learning Services: Expands the capabilities of in-database machine learning by adding support for Python models and scripts alongside R.
Other notable features:
- Query Store hints: Provides a mechanism to influence query execution plans based on historical insights from the Query Store, optimizing performance for specific workloads.
- Temporal tables: Automatically tracks and manages data changes over time, simplifying temporal data management and analysis.
- Expanded ledger capabilities: Enhances support for blockchain-based applications with new features for consensus algorithms and tamper-evident data storage.
Azure-connected features:
- Pay-as-you-go model: Offers a flexible consumption-based licensing model for SQL Server on Azure, aligning costs with actual usage.
- Azure SQL Managed Instance link: Enables seamless integration between SQL Server instances and Azure SQL Managed Instance for hybrid scenarios.
