This occurs when a database management system caches a certain search path or plan and uses that cached plan for subsequent queries, which can cause performance problems for non-uniform data distributions. The feature is particularly useful for discovering trend lines in data, when it’s not necessary to crunch every single number before making decisions based on general trajectory.Īnother pain point solved by SQL Server 2022 is a type of query problem called a parameter-sensitive plan. SQL Server 2022 extends that by offering an additional approximate percentile equivalence, which allows for even lighter-weight calculations that fall within a reasonable error range. Previously, SQL Server 2019 helped mitigate this resource-usage issue by building in an “approximate count distinct” function, which quickly calculated approximations using a smaller memory footprint, rather than relying on exact operation equivalents, which can take significantly longer. Organizations are inundated with torrents of data, which in turn create massive data sets that take an increasing amount of time and resources to analyze, even with advanced algorithms and processors. One groundbreaking new feature is called approximate percentile. So SQL Server 2022 is introducing the next generation of Intelligent Query Processing (IQP) capabilities. Without the ability to analyze data, though, information goes to waste. “This is a very practical use of blockchain technology that will have huge benefits for companies.” “The great thing is that you can always backtrack to a previous version of the data, because it will have been moved to an immutable ledger,” says Lopes. In regulated industries like finance and insurance, where auditors need to verify a database’s integrity, this is a vital feature. This feature tracks any potential data changes from malicious actors while also enabling third parties to confirm if anything has been compromised.
Ledger uses the concept of blockchains built into SQL Server to track changes to the database using crypto hashing.
To continue keeping data secure both in the cloud and on-premises, SQL Server 2022 includes several innovations. Over the past ten years, SQL Server has had fewer vulnerabilities than the competition 1. Global losses from cybercrime totaled more than $1 trillion in 2020, according to a report by the Center for Strategic and International Studies, double the amount from only two years before. SQL Server 2022 also enhances digital security-a paramount need for businesses today. Users can also expect database backup speeds that are 230 percent faster than with previous versions, which is critical to helping database administrators and developers get to production quicker. This data-compression technology enables faster online transactional processing (OLTP) operations in SQL Server while reducing the impact on the system’s transaction throughput. As a result, one innovative outcome is the use of Intel® QuickAssist Technology (QAT) for the SQL engine, a feature that offloads data compression on SQL Server bare-metal platforms or virtual machines. To optimize SQL Server 2022 on a hardware level, Microsoft engineers worked closely with Intel. “With every version of SQL Server, we want to give them the tools to gather and explore the data wherever they need it, all while keeping it safe.” “Our driving force is to ensure a customer’s data is where they need it to be, whether that’s due to customer preferences, regulatory requirements, or just ease of use,” says Lopes. Overall, it includes even more game-changing upgrades to query processing, security, and disaster recovery-providing a holistic opportunity for companies to harness data and leverage it for growth. The system, available in 2022, is part of Microsoft’s broader vision for an end-to-end data platform providing customers with operational databases, analytics and governance, and the ability to seamlessly bridge on-premises deployments to the cloud. Microsoft is hoping to bolster this performance advantage with the newly announced SQL Server 2022, which-with the help of Microsoft and Intel engineers-will be optimized for the Intel 3rd Generation Xeon Scalable processors. “It’s a testament to our engineers, who continually enhance the database engine with built-in query intelligence so that customers can gain performance with no application changes required.” “They asked, ‘What the heck did you guys do?’” laughs Bob Ward, Principal Architect for the Microsoft Azure Data team, which oversees the SQL Server and Azure Data technology architecture.
