In today’s environment, SQL is amongst the most in-demand abilities. Massive volumes of data are gathered every day, and in order to generate relevant information, one must connect with these databases. SQL 2022 is shaping up to be a considerable step forward from the SQL 2019 enhancements.

On November 2, 2021, Microsoft revealed the private release of SQL Server 2022, with a general availability date of sometime in the Current Year 2022. The entire specifics of this brand-new edition will be published in due time, as it is now in private preview. These announcements are noteworthy because SQL Server 2019 was launched three years ago, and Microsoft has already outlined some of the key features that the audience might expect. Let’s make a cup of coffee and get this fast review of performance optimization features of SQL started.


To gain in-depth knowledge with practical experience in SQL server, then explore SQL server Training.

What is Performance Optimization?       

Performance optimization, often known as SQL performance tuning, is the process of improving the speed of your server by optimizing SQL queries. Its overall purpose is to reduce the time it takes for a user to receive a response after submitting a query, as well as the number of resources needed to do so. There isn’t a one-size-fits-all solution to SQL performance tweaking, and it’s more of a set of methods that use a variety of approaches, tools, and procedures. In the subqueries course, the concept of employing a faster-running query to achieve the same desired result set was presented. These features will show you how to recognize when and how to improve your queries.

Performance Optimization features of SQL Server 2022:

  • Spin up to an Azure SQL Managed Instance:

You can connect a database to the cloud with just a few taps. This step creates a disaster recovery or read-only workload offloading Availability Group (AG) between an on-premises SQL Server and an Azure SQL Managed Instance (MI). You can then fail over to the MI and back manually. A backup from a MI can also be restored to SQL Server 2022. With Azure SQL Managed Instances, you can save money, effort, and time by letting Microsoft handle your hardware or virtual machines across various data centers.

The Azure SQL Managed instance makes disaster recovery deployment and administration easy as appropriate link capabilities. Multi-subnet clusters and dispersed availability groups, both of which need sophisticated settings, are now available. The Azure SQL Managed Instance databases can also be reloaded to your SQL Server. This is indeed a spanking-new restoration mechanism not found in earlier SQL Server editions.

  • Plan Optimization using Sensitive Parameter Parameters:

In SQL Server 2019 and before, several stored procedures are particularly sensitive to the input parameter values used the first time the code was run. To put it another way, it’ll be a solution to the performance problem that parameter sniffing causes. Don’t get it mixed up: It’s as if sniffing parameters is a negative thing. For the most part, parameter sniffing has worked successfully in the actual world. However, there are situations when a query or stored procedure generates and caches an execution plan that isn’t optimal. There have been a number of approaches to this problem, but none of them is perfect.

The most intriguing aspect is that SQL Server will now cache several plans for numerous parameters with separate execution plans from now on. It’ll be fascinating to see how SQL Server handles this internally and avoids the cache bloating problem.

  • Improvements to the Query Store:

Query Store will be automatically enabled on new databases in SQL Server 2022. This demonstrates Microsoft’s faith in the benefits of Query Store. You’ll have to enable Query Store manually if you restore a database from an older version of SQL Server. Query Store, for example, is now available for all new databases. Another interesting addition is that-

  • The Query Store can now assist in resolving performance issues relating to MAXDOP (maximum degree of parallelism) settings, memory grants, and so on.
  • To adjust and enhance query processing plans, the clustering estimator uses a feedback cycle.
  • Finally, Query Store now supports availability group (AG) read-only replicas, as well as query hints that can be used directly within the Query Store to boost query speed without requiring code changes.
  • TempDB and Latch:

While performing SQL Server Performance Tuning, one out of every ten clients has TempDB and Latch difficulties. There are several ways to handle this problem, but it would be preferable if it did not exist in the first place. Finally, there are a few enhancements planned in SQL Server 2022 for this area.

Enhancements to the TempDB database and Memory Optimized TempDB Metadata in SQL Server 2022 address these concerns. Experts believe that with the release of this new version, clients will no longer have to deal with these challenges.

  • Azure Synapse Link:

To move data from on-premises databases like SQL Server to Synapse, you have to use ETL. As we all know, setting up and running an ETL pipeline takes time, and the results often lag behind current events. For SQL Server 2022, Azure Synapse Link delivers-

  • Automatic change feeds detect SQL Server changes and provide them to Azure Synapse Analytics. It enables near-real-time analysis and hybrid transactional and analytical processing with minimal impact on operational systems.
  • Because the automated change keeps feeding only new or unique data, data transit is significantly faster in SQL Server 2022, providing for close real-time analytics with low interference on the source database’s performance.
  • Once the data is in Synapse, you can mix it with a variety of other data sources, irrespective of size, complexity, or structure, and perform advanced analytics on it all using Azure Machine Learning, Spark, or Power BI.
  • Azure Purview Integration:

Microsoft’s inaugural feature set has been developed into a more comprehensive data governance platform. Purview now integrates more tightly with SQL Server and Azure SQL. We’re delighted to announce that SQL Server is now integrated with Azure Purview for improved data discovery and the dismantling of data silos. You’ll be able to do the following with this integration-

  • Scanning your on-premises SQL Server for nothing to obtain metadata is simple.
  • Use typical filter labelling and tags to categorize data such as PII data or HIPAA data.
  • Build and maintain certain SQL Server access rights with a single Azure console of purview.
  • Blockchain Functionality with SQL Server Ledger:

The Azure SQL Database ledger feature offers to encrypt functionality in your database. You can cryptographically certify that your data has not been altered with to outside parties, such as auditors or other business partners.

  • Auditing procedures take a long time to complete. On-site inspections of established deveprocesses, such as checking audit logs, examining verification, and evaluating access controls, are required during auditing.
  • Auditors receive cryptographic confirmation of data integrity from Ledger. This proof may make the auditing process go more smoothly.
  • A business process’ status must be shared among several companies. These systems have a hard time figuring out how to share and trust data. Traditional blockchains, such as Ethereum, are becoming increasingly popular among businesses.
  • For these networks, Ledger has a solution. Users can check the authenticity of data stored centrally without the added complexity and performance costs.
  • The potential to retrieve the data on the blockchain without losing efficiency is a hurdle when a blockchain network is required for multi-party business activity.
  • Data from the blockchain is replicated to an off-chain repository, such as a database. Ledger ensures the accuracy of blockchain networks’ off-chain storage, ensuring complete data confidence throughout the system.


SQL Server 2022 appears to be a big update, even based on the limited information we have thus far. Customers using Azure SQL should be able to use a number of the new features in the next major release. Microsoft has a history of introducing new features to the Azure cloud before they are available on-premises. SQL Server 2022 has a variety of capabilities that can help a business develop and expand if used correctly. On the other hand, expert assistance can assist you in pairing it with appropriate extensions, tools, and other resources. SQL Server is a new platform that many people may use. Get your hands on a copy of the sneak peek as soon as possible!
