Microsoft SQL Server 2022 (Preview)

What’s New in Microsoft SQL Server 2022?

Microsoft SQL Server 2022 is loaded with exciting new features and enhancements to the core database engine, performance, and security. The following diagram gives a high-level representation of SQL Server 2022.

On-Prem SQL instance Business Continuity using Azure SQL Managed Instance

• The Azure SQL Managed instance as a new link feature simplifies the configuration and management for disaster recovery. Currently, you can use multi-subnet clusters or distributed availability groups that require complex configurations. The new link feature uses a built-in distributed availability group (DAG) to replicate data to existing Azure SQL quickly Managed instances. DBAs do not spend much time on lengthy configurations or DR instance maintenance
• The link-in feature enables you to read scale-out queries as well to the DR servers. Therefore, you can offload heavy read requests to the Azure SQL Managed Instance
• You can failover from on-premises SQL Instance to Azure SQL Managed instance (DR) or vice-a-versa
• You can restore (move) the database from the Azure SQL Managed Instance (DR) to on-premises SQL Server
  • Backup database from Managed instance to the storage account
  • Restore database in the on-prem instance from the backup file stored in a storage account

Seamless analytics over on-prem operational data

• Hybrid transactional processing
• Analytical processing
• Near real-time analysis
• Minimal impact on the source (operational) system

Azure Purview integration

• Automatically scan your on-premises SQL Server for free to capture metadata
• It can automatically scale on-premises SQL Server for capturing metadata
• You can use in-built or custom data classifiers and use Microsoft Information Protection sensitivity labels
• Configure and control access rights to SQL Server

SQL Server Database Ledger with blockchain functionality

• Intelligent Query Processing for a parameterized query: Parameter sniffing is a problematic issue in stored procedures with different parameters. SQL Server stores(cache) an execution plan based on a parameter that might not work efficiently with another parameter. The current SQL Server version can cache a single execution plan for a stored procedure. Therefore, the query execution with a different parameter can create a performance issue. SQL 2022 Parameter Sensitive Plan Optimization feature enables storing multiple cache plans for a single parameterized statement. SQL Server chooses the optimized execution plan based on the incoming parameter value. You do not require any code change for using the Parameter Sensitive Plan Optimization feature. Change the compatibility level 160 for the required database and this feature is automatically enabled as a database scoped feature
• Query Store: SQL Server 2022 enables the Query Store feature, by default, for every database
• Peer-to-Peer replica conflict: In the multi-write database environment, users can change the local database data and be replicated in a two-way flow of updates to remain. However, if multiple customers update the same row simultaneously at different write replicas, it can create a data conflict that could stall the whole operation
