Hello Dev! Are you ready for the latest release of SQL Server? SQL Server 2022 has just been released, and it comes packed with an array of new features that are sure to make your life easier. In this journal article, we’ll explore the new features that SQL Server 2022 has to offer. We’ll give you an idea of what each feature entails and how they can benefit your work. Let’s begin!
1. Scalability
The first new feature in SQL Server 2022 is scalability. This feature allows for horizontal scaling on Linux and containers. With the new SQL Server 2022, you can add nodes to a cluster without any downtime. This can be done by adding nodes to the cluster using Kubernetes or other container orchestration tools. This feature can be used in the on-premises environment or in the cloud.
The second feature under scalability is resumable online index rebuilds. This feature allows you to pause and resume large index rebuilds, which saves you time and resources.
The third feature is intelligent query processing (IQP). IQP improves query performance by making query execution plans more efficient. With this feature, SQL Server can automatically choose the best execution plan for your query.
The fourth feature is native support for containers. With this feature, you can run SQL Server in a container, which makes it easier to deploy and manage your SQL Server instances.
The fifth feature under scalability is enhanced automatic tuning. This feature allows you to fine-tune your SQL Server instance’s performance by automatically adjusting configuration settings based on workload patterns.
2. Performance
The second new feature in SQL Server 2022 is performance. This feature includes several enhancements that improve query performance and reduce resource consumption.
The first feature under performance is row-level security. With this feature, you can control access to individual rows in a database table based on user permissions. This feature can be used in scenarios where different users have different levels of access to the same data.
The second feature is memory-optimized tempdb metadata. This feature improves the performance of tempdb metadata by using memory-optimized tables. This feature is useful in scenarios where tempdb is a bottleneck.
The third feature is accelerated database recovery. This feature improves database recovery times by reducing the amount of time it takes to roll back a long-running transaction. It also reduces the amount of transaction log generated during a rollback.
The fourth feature under performance is persistent memory support. With this feature, you can take advantage of Intel Optane DC persistent memory to improve database performance. This feature can be used in scenarios where the data set is too large to fit entirely in memory.
The fifth feature is UTF-8 characters support. With this feature, you can store and retrieve UTF-8 encoded characters natively, which improves performance and saves storage space.
3. Security
The third new feature in SQL Server 2022 is security. This feature includes several enhancements that improve the security of your SQL Server instances.
The first feature under security is always encrypted with secure enclaves. This feature allows you to encrypt sensitive data while it’s being processed in memory using secure enclaves. This feature provides an additional layer of security to sensitive data.
The second feature is dynamic data masking. With this feature, you can mask sensitive data in a database table based on user permissions. This feature can be used in scenarios where different users have different levels of access to the same data.
The third feature is Azure AD authentication for SQL Server on Linux. With this feature, you can use Azure AD to authenticate users in a SQL Server instance running on Linux. This feature makes authentication more secure and easier to manage.
The fourth feature under security is robust auditing. This feature allows you to audit SQL Server activities and provides you with detailed audit logs. This feature is useful in scenarios where regulatory compliance requires auditing of SQL Server activities.
The fifth feature is always encrypted with secure enclaves. This feature allows you to encrypt sensitive data while it’s being processed in memory using secure enclaves. This feature provides an additional layer of security to sensitive data.
4. Data Management
The fourth new feature in SQL Server 2022 is data management. This feature includes several enhancements that improve the management of your SQL Server instances.
The first feature under data management is enhanced PolyBase. This feature allows you to perform distributed queries across multiple data sources, including Hadoop and Oracle. This feature makes it easier to integrate data from different sources into your SQL Server instances.
The second feature is intelligent query processing (IQP). IQP improves query performance by making query execution plans more efficient. With this feature, SQL Server can automatically choose the best execution plan for your query.
The third feature is enhanced machine learning services. This feature provides new algorithms and tools for machine learning, which makes it easier to integrate machine learning into your SQL Server instances.
The fourth feature under data management is Accelerated Database Recovery. This feature improves database recovery times by reducing the amount of time it takes to roll back a long-running transaction. It also reduces the amount of transaction log generated during a rollback.
The fifth feature is intelligent performance optimization. This feature uses machine learning to identify and optimize SQL Server instances’ performance. This feature can be used to improve query performance and reduce resource consumption.
