The ability to collect, organize and evaluate data quickly is critical today. However,
Microsoft has strategically planned for the same long ago. It came up with a high-availability
database, Structured Query Language, in the year 1989 to bring good connectivity and
analytical capabilities to any organization.
Since then, Microsoft SQL Server has expanded its feature set and functionalities with each new
edition. SQL Server evolves over time as new features are added that are necessary for
business management techniques at the moment. Polybase, long-line security, and rapid speed
were all trademarks of SQL Server starting in 2016. In 2017, SQL Server got more Linux-
friendly by merging machine learning methods with flexible query processing services. In the
year 2019, the new version, data abstraction, and categorization were improved.
If you’re expecting an update or a whole new system in your data center, you should be
conscious of SQL Server 2022’s new capabilities and be prepared to take benefit of them as
soon as possible.

Let’s start by looking at some of the most exciting new features and improvements in
SQL Server 2022:
Although most of the product’s features are still under wraps, the material made public has
revealed several intriguing performance-based capabilities in SQL Server 2022.
Intelligent Query Processing and Query Store:
Parameter sniffing is a problem with stored procedures of many parameters together. So, the
all-new databases created on the server with SQL Server 2022 will have access to the Query
Store. An execution plan is cached by SQL Server depending on a parameter that may or may
not be compatible with another parameter. This illustrates Microsoft’s faith in Query Store’s
benefits, such as:
- The Query Store is manually activated if a database prepared with an earlier version of
SQL is accessed.
- Intelligent Query Processing (IQP) has been implemented to ensure better query
patterns and memory grant feedback. Feedback loop for MAXDOP and C.E. models using
Query Store to automatically adjust and fix problems with typical MAXDOP and C.E.
model query patterns.
- Query Store now supports A.G. read-only replicas, allowing you to monitor the
performance of your read-only workloads. You’ll also be able to leverage Query Store
hints to build query plans more easily without changing any code.
Query store: Every database in SQL Server 2022 has the Query Store functionality enabled by
The conflict between peer-to-peer replicas: If numerous users change the same row at
separate write replicates at the same time, a data conflict may occur, causing the entire
transaction to halt. Users can edit local database data and have it replicated in a two-way flow
of updates in an inter database system.
Plan Optimization using Sensitive Parameters:
In SQL Server 2019 and before, some stored procedures are particularly sensitive to the input
parameter values used the first time the set of instructions was executed.
SQL Server 2022’s database engine now supports several cached plans for the same query,
with the only difference being the parameter values. They are as follows:
- Instead of having a single plan to meet all requests, SQL Server may select the best plan
for the work at hand.
- Using the reload option or allocating the values of the input parameter to variables
within the procedure will help you avoid having to change your code.
- While parameter sniffing normally works well, it can occasionally cause significant
performance predictor variables for no apparent reason. In case a poor query plan is
employed, performance starts out good but degrades very quickly. There are a variety
of approaches that can be used to try to avoid this prevalent issue.
- Parameter Sensitive Plan Optimization will cache numerous parameter-sensitive active
query plans per stored procedure or parameterized query.
● Link to Azure Synapse:
Microsoft has created a bunch of tools available to help business users better analyze their
data. One of the difficulties with dashboards and reports is the strain these queries can put on
SQL Server, potentially slowing down the performance of your transaction database.
Data is sent from an on-premise SQL Server to Synapse using the Azure Synapse Link. It keeps
track of changes on the server and transmits them to Azure Synapse Analytics.
It increases data interaction with other strong analytic packages and speeds up data transit.
You can utilize Azure Synapse Link with SQL Server 2022 to quickly move data from SQL
Server 2022 to Azure Synapse Analytics. This helps you to keep your reporting dataset up to
date while also removing these operations from your production databases.
● Latching and TempDB:
Using TempDB to manage temporary objects on highly active SQL Servers can create a
constraint and lead processes to become stuck. Despite the fact that it can be handled in a
variety of ways, the practice took a considerable amount of time and effort. SQL Server 2022
upgraded the TempDB database and Memory Optimized TempDB Metadata to address these
SQL Server 2022 includes system page latch concurrency features to prevent Global Allocation
Map contention and allow concurrent Shared Global Allocation Map changes.
● Azure SQL Managed Instance:
SQL Server 2022 adds new seamless integration connection features to the Azure SQL
managed instance to ensure database reliability. You can connect a database to the cloud with
just a few clicks.
This saves money, time, and effort by removing the technicalities of data storage hardware and
virtual computers. As a result of this feature, you may set up D.R. for your on-premises
database using an Azure SQL Managed Instance to maintain your data in sync in the event of a
failure. What more Azure update offers:
- Disaster recovery configuration and maintenance are made easier with the Azure SQL
Managed instance as appropriate link capabilities. Multi-subnet clusters or scattered
availability groups, which necessitate complex configurations, are now accessible.
- Using a built-in distributed availability group, the new connection functionality
replicates data to existing Azure SQL quickly Managed instances (DAG). Long
configurations and D.R. instance maintenance take up a lot of time for DBAs.
- Additionally, you can restore the Azure SQL Managed Instance databases to your SQL
Server. This brand-new restoration mechanism wasn’t available in previous SQL Server
editions as well.
● Ledger in SQL Server:
SQL Server 2022 introduces a new ledger feature that allows you to retain an immutable
record of data modifications. It can prevent data manipulation by unauthorized operations. It is
perfect for apps that need to store sensitive financial data like banking transactions. SQL Server
now features a distributed ledger and improvements to always encrypted, secure encrypted
connections and more granular permissions and roles.
● Cloning with Multiple Writes:
Earlier, when rewritten data clashed with various clones of the same database, the dispute had
to be manually resolved. SQL Server 2022, on the other hand, addresses this problem by adding
the concept of ‘last write wins.’ As a result, if a disagreement between duplicates arises, the
most recent rewrite will take precedence and be copied to all copies.
● Improvements in Surveillance and Management:
The basic feature set of Microsoft has been expanded to create a more comprehensive data
governance platform. Preview now integrates more tightly with SQL Server and Azure SQL,
allowing you to scan SQL Server for metadata.
Classify data using common classifier labels and tagging (PII or HIPAA data), and configure and
control specific SQL Server access rights and privileges from a single Azure Purview console.
The new functionality uses blockchain technology to generate an immutable record of data
changes over time. This protects data from manipulation, which is critical in specific situations
and use cases, and it also helps with internal and external audits.
Benefits of SQL Server 2022:
● Analyzes operational data in a seamless manner: To analyze your data, you can use
Azure Machine Learning, Spark, or Powerful B.I.
● Visibility across Your Entire Data Infrastructure: This allows users to scan data with
sensitive markings and custom classifications quickly and simply.
● Azure helps to ensure business continuity: The SQL Server 2022 allows you to easily
link and replicate data to and from the cloud. So effective that you won’t lose data.
● Secured data: Using the centralized blockchain approach, your data will always be safe
from threats and intrusions.
You should be excited about Microsoft SQL Server 2022 Private Preview, which is now
available for early access for now. If implemented effectively, features can aid in a company’s
growth and innovation. On the other hand, expert assistance can assist you in pairing it with
valuable extensions, tools, and other resources. It’s a fun way to make the best decision for
your business. So this was all we went over to collect the features of SQL 2022 for you.
