SQL Server 2022 New Features
SQL Server 2022 is a relational database management system (RDBMS) developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network (including the Internet).
Microsoft markets at least a dozen different editions of Microsoft SQL Server. These software's are aimed at different audiences and for workloads ranging from small single-machine applications to large Internet-facing applications with many concurrent users. The most recent release is SQL Server 2017.
SQL Server 2022 has been the focus of several recent enhancements. These include an improved buffer pool extension that allows data from frequently accessed tables to be stored in memory; faster query performance with columnstore indexes; new JSON support; and better security.
In addition, Microsoft has added support for big data workloads with the inclusion of Hadoop Distributed File System (HDFS) integration. Additionally, the company has worked to improve scalability by introducing scale-out capabilities, forAlwaysOn Availability Groups.
SQL Server is a central part of the Microsoft data platform. It is the foundation of Microsoft's entire business intelligence stack and enables end-to-end mobile BI solutions. The release of SQL Server 2022 brings with it many new features and enhancements that will make it easier for organizations to adopt a cloud-first approach to their data management needs.
In this article, we'll look at some of the most important new features in SQL Server 2022 and how they can benefit your organization.
Improved Buffer Pool Extension
As part of SQL Server 2022, improvements were made to the buffer pool extension (BPE) to provide better performance and stability. These changes include:
- Improving the algorithms used to allocate and deallocate memory for BPE should result in better performance.
- Adding support for dynamic management views (DMVs), so you can monitor the performance of your BPE deployment.
- Enhancing the error handling and recovery capabilities of BPE to make it more robust.
Microsoft is also introducing a new feature called buffer pool import (BPI), which allows you to import data from another SQL Server instance into your BPE deployment. BPI can be helpful if you want to move data from an on-premises instance of SQL Server to a cloud-based instance or vice versa.
Buffer pool extension is a feature of SQL Server that allows you to use non-volatile memory (such as SSDs) to extend the size of the buffer pool. As a result, BPI can improve performance by reducing the need to read data from a disk. Buffer pool extension is available in all editions of SQL Server 2022.
Faster Query Performance
SQL Server 2022 includes a number of enhancements that can improve query performance. For example, the new Adaptive Query Processing (AQP) feature can automatically tune query execution plans based on feedback from previous executions. As a result, AQP can help to optimize performance for frequently-run queries. In addition, the new Query Store feature can provide visibility into query performance over time, allowing you to identify and troubleshoot potential performance issues. Finally, the updated optimizer engine in SQL Server 2022 can take advantage of newer hardware capabilities to improve query performance.
These are just a few of the many features in SQL Server 2022 that can help boost query performance. Be sure to explore all the new features and capabilities in SQL Server 2022 to see how they can help improve your overall performance.
Adaptive Query Processing (AQP) is a new feature in SQL Server 2022 that automatically adjusts query execution plans based on feedback from actual execution statistics. AQP allows the database engine to "tune" queries more accurately for optimal performance.
AQP works by constantly monitoring query execution and collecting statistics about what operations are being performed and how long they take. Based on this information, the database engine can then make adjustments to the query execution plan on-the-fly to improve performance.
AQP is designed to work with both traditional SQL queries and new "intelligent" queries that use machine learning algorithms to generate optimal execution plans automatically. In either case, AQP can significantly improve performance over traditional query optimization techniques.
AQP is transparent to the user and requires no changes to existing queries or application code. AQP is also compatible with all existing SQL Server features and tools, including third-party monitoring and administration tools.

SQL Server 2022 adds built-in support for JSON, making it easier to work with data in this popular format. This new support includes a JSON data type, enabling you to store and query JSON data directly in the database. In addition, SQL Server 2022 provides a set of built-in functions for working with JSON data, making it easy to parse and query JSON data within your SQL queries.
JSON support in SQL Server 2022 makes exchanging data between different applications and systems easy. For example, JSON support can be instrumental when working with web-based applications that often exchange data in JSON format. With the built-in JSON support in SQL Server 2022, you can easily move data back and forth between your database and these applications without having to convert the data to another format.
In addition, the built-in JSON support in SQL Server 2022 makes it easy to query and manipulate JSON data directly within the database. The new JSON functions allow you to quickly parse and query JSON data, making it easy to find the data you need within your database. In addition, with these new functions, you can easily update and delete JSON data within your database.
SQL Server 2022 provides several benefits for working with JSON data. With built-in support for this popular data format, you can easily exchange data between different applications and systems. In addition, the new JSON functions make it easy to query and manipulate JSON data within your database.
Enhanced Security Features
SQL Server 2022 introduces several new security features to help keep your data safe. Here are some of the highlights:
- SQL Server auditing has been enhanced to track activity more effectively and provide better visibility into who is accessing your data.
- A new Data Masking feature helps protect sensitive data by obscuring it from view.
- The Transparent Data Encryption (TDE) feature has been improved to encrypt data at rest more effectively.
- SQL Server 2022 also includes several other security enhancements, such as improved Windows Authentication and Kerberos delegation support.
These new security features will help you keep your data safe from unauthorized access and ensure compliance with regulations such as GDPR. For more information, see the SQL Server Security Guide.
How it works
SQL Server 2022 introduces several new security features that aim to improve the security of your database. Let's take a closer look at how these features work and how they can help you secure your data.
One of the most important changes in SQL Server 2022 is how authentication is handled. In previous versions of SQL Server, the Windows Authentication Services (WAS) handled authentication. However, in SQL Server 2022, Microsoft introduced a new authentication service called Active Directory Authentication Library (ADAL).
ADAL provides a number of benefits over WAS, including improved security and better performance. Furthermore, ADAL integrates with other Microsoft products such as Azure Active Directory, making it easier to manage user authentication across your organization.
Another significant change in SQL Server 2022 is the introduction of Always Encrypted. Encrypted is a new feature that allows you to encrypt your data at rest and in transit. Always Encrypted uses two different types of keys: a column master key (CMK) and a column encryption key (CEK).
The CMK is used to encrypt the CEK, which is then used to encrypt the data. The CMK can be stored in either a hardware security module (HSM) or in Azure Key Vault. The CEK is stored with encrypted data and is only decrypted when it is needed for use.
Always Encrypted provides several benefits over traditional encryption methods, including improved security and performance. Furthermore, it is transparent to applications, meaning you do not need to make any changes to your code to use it.
SQL Server 2022 also introduces a new feature called Dynamic Data Masking (DDM). DDM allows you to mask sensitive data in your database, such as credit card or social security numbers. When data is masked, it is replaced with a random value consistent across all column rows.
DDM ensures that sensitive data is hidden from users who should not have access to it. In addition, DDM is transparent to applications and does not require any changes to your code.
Finally, SQL Server 2022 introduces several other minor security improvements, such as creating user-defined roles and auditing system improvements. These changes aim to further improve the security of your data and make it easier to comply with regulations such as the General Data Protection Regulation (GDPR).
Support for Big Data Workloads
SQL Server 2022 will include support for big data workloads, allowing organizations to process and analyze large amounts of data more efficiently. This new capability will make it easier to manage big data projects and improve performance and scalability.
SQL Server 2022 will include several new features to support big data workloads, including:
- A new Big Data Cluster feature will allow organizations to deploy and manage a cluster of SQL Server instances, HDFS, and Spark in a single integrated system.
- Improved performance and scalability for big data workloads through enhancements to the SQL Server engine and query processor.
- A new Big Data File Format (BDF) will help improve performance and efficiency when working with large amounts of data.
- Enhanced security and privacy features, such as Always Encrypted with Secure Enclaves, to help protect sensitive data.
With these new capabilities, SQL Server 2022 will be a powerful platform for organizations to build big data solutions.
How do you manage workloads
There are two main ways to manage big data workloads on SQL Server: through the use of traditional database management tools or the use of Hadoop.
Traditional database management tools are typically used to manage structured data, while Hadoop is often used to manage unstructured data. However, both approaches can be used to manage big data workloads.
When deciding which approach to use, it is important to consider the type of data that will be managed, the size of the data set, and the available resources. In some cases, it may be necessary to use traditional database management tools and Hadoop to manage all of the data effectively.
If you are looking for a tool to help you manage big data workloads on SQL Server, consider using Hadoop. Hadoop is an open-source framework that can process and analyze large data sets. In addition, Hadoop is scalable and can be deployed on a variety of hardware platforms.
In addition, Hadoop includes a number of tools that can manage big data workloads. These tools include the following:
- Hive:A data warehouse system that uses SQL-like queries to access and process data stored in HDFS.
- Pig:A high-level programming language that can write MapReduce programs.
- Sqoop:A tool that imports data from relational databases into HDFS.
- Flume:A tool that ingests data into HDFS.
Hadoop is flexible and can be deployed on a variety of hardware platforms.
