With a seamless integration between operational stores in SQL Server 2022 and Azure Synapse Analytics dedicated SQL pools, Azure Synapse Link for SQL enables you to run analytics, business intelligence and machine learning scenarios on your operational data with minimum impact on source databases with a new change feed technology.

SQL Server 2022 introduces new object storage integration to the data platform, enabling you to integrate SQL Server with S3-compatible object storage, in addition to Azure Storage. The first is backup to URL and the second is Data Lake Virtualization.

Query different types of data on different types of data sources from SQL Server.

Link to Azure SQL Managed Instance

Connect your SQL Server instance to Azure SQL Managed Instance.

Create an Always On availability group that:

- Manages its own metadata objects (users, logins, permissions, SQL Agent jobs etc.) at the availability group level in addition to the instance level.

- Includes specialized contained system databases within the availability group.

Now using multiple TCP connections for better network bandwidth utilization across a remote link with long tcp latencies.

Microsoft Defender for Cloud integration

Protect your SQL servers using the Defender for SQL plan. Defender for SQL plan requires that SQL Server Extension for Azure is enabled and includes functionalities for discovering and mitigating potential database vulnerabilities and detecting anomalous activities that could indicate a threat to your databases. Learn more on how Defender for SQL can protect your entire database estate anywhere: on-premises, hybrid, and multicloud environments.

Apply Microsoft Purview access policies to any SQL Server instance that is enrolled in both Azure Arc and the Microsoft Purview Data Use Management.

- Newly introduced SQL Performance Monitor, and SQL Security Auditor roles align with the principle of least privilege using Microsoft Purview access policies.

The ledger feature provides tamper-evidence capabilities in your database. You can cryptographically attest to other parties, such as auditors or other business parties, that your data hasn't been tampered with

Use Azure Active Directory (Azure AD) authentication to connect to SQL Server.

Support for JOIN, GROUP BY, and ORDER BY, and for text columns using UTF-8 collations in confidential queries using enclaves. Improved performance.

New granular permissions improve adherence with the Principle of Least Privilege

New built-in server-level roles enable least privileged access for administrative tasks that apply to the whole SQL Server Instance

Granular UNMASK permissions for Dynamic Data Masking.

New support for import and export of PFX file formatted certificates and private keys. Ability to backup and restore master keys to Azure Blob Storage. SQL Server-generated certificates now have a default RSA key size of 3072-bits.

New MS-TDS protocol iteration:

- Makes encryption mandatory

- Aligns MS-TDS with HTTPS making it manageable by network appliances for additional security

- Removes MS-TDS / TLS custom interleaving and enables usage of TLS 1.3 and subsequent TLS protocol versions.

System page latch concurrency enhancements

Concurrent updates to global allocation map (GAM) pages and shared global allocation map (SGAM) pages reduce page latch contention while allocating/deallocating data pages and extents. These enhancements apply to all user databases and especially benefit tempdb heavy workloads.

Improves the performance of buffer pool scan operations on large-memory machines by utilizing multiple CPU cores. Learn more about Operations that trigger a buffer pool scan may run slowly on large-memory computers.

Ordered clustered columnstore index (CCI) sorts the existing data in memory before the index builder compresses the data into index segments. This has the potential of more efficient segment elimination, resulting in better performance as the number of segments to read from disk is reduced.

All columnstore indexes benefit from enhanced segment elimination by data type. Data type choices may have a significant impact on query performance based common filter predicates for queries on the columnstore index. This segment elimination applied to numeric, date, and time data types, and the datetimeoffset data type with scale less than or equal to two. Beginning in SQL Server 2022 (16.x), segment elimination capabilities extend to string, binary, guid data types, and the datetimeoffset data type for scale greater than two.

Improve memory management in large memory servers to reduce out-of-memory conditions.

In previous versions of SQL Server, if the next growth is more than 1/8 of the current log size, and the growth is less than 64MB, four VLFs were created. In SQL Server 2022 (16.x), this behavior is slightly different. Only one VLF is created if the growth is less than or equal to 64 MB and more than 1/8 of the current log size.

- ParallelRedoThreadPool : Instance level thread pool shared with all databases having redo work. With this, each database can take the benefit of parallel redo. Limited to max 100 thread earlier.

- Parallel redo batch redo - Redo of log records are batched under one latch improving speed. This improves recovery, catchup redo, and crash recovery redo.

Reduced the incidents of a single page being promoted to eight pages when populating the buffer pool from storage, causing unnecessary I/O. The buffer pool can be populated more efficiently by the read-ahead mechanism. This change was introduced in SQL Server 2022 (all editions) and included in Azure SQL Database and Azure SQL Managed Instance.

Spinlocks are a huge part of the consistency inside the engine for multiple threads. Internal adjustments to the Database Engine make spinlocks more efficient. This change was introduced in SQL Server 2022 (all editions) and included in Azure SQL Database and Azure SQL Managed Instance.

Virtual File Log (VLF) is an abstraction of the physical transaction log. Having a large number of small VLFs based on log growth can affect performance of operations like recovery. We changed the algorithm for how many VLF files we create during certain log grow scenarios.

In general, transaction log files cannot benefit from instant file initialization (IFI). Starting with SQL Server 2022 (all editions) and in Azure SQL Database, instant file initialization can benefit transaction log growth events up to 64 MB. The default auto growth size increment for new databases is 64 MB. Transaction log file autogrowth events larger than 64 MB cannot benefit from instant file initialization.

The intelligent query processing (IQP) feature family includes features that improve the performance of existing workloads with minimal implementation effort.

Query Store on secondary replicas enables the same Query Store functionality on secondary replica workloads that is available for primary replicas. Learn more in Query Store for secondary replicas.

Query Store hints leverage the Query Store to provide a method to shape query plans without changing application code. Previously only available on Azure SQL Database and Azure SQL Managed Instance, Query Store hints are now available in SQL Server 2022 (16.x). Requires the Query Store to be enabled and in "Read write" mode.

Memory grant feedback adjusts the size of the memory allocated for a query based on past performance. SQL Server 2022 introduces Percentile and Persistence mode memory grant feedback. Requires enabling Query Store.

- Persistence: A capability that allows the memory grant feedback for a given cached plan to be persisted in the Query Store so that feedback can be reused after cache evictions. Persistence benefits memory grant feedback as well as the new DOP and CE feedback features.

- Percentile: A new algorithm improves performance of queries with widely oscillating memory requirements, using memory grant information from several previous query executions over, instead of just the memory grant from the immediately preceding query execution. Requires enabling Query Store. Query Store is enabled by default for newly created databases as of SQL Server 2022 CTP 2.1.

Automatically enables multiple, active cached plans for a single parameterized statement. Cached execution plans accommodate largely different data sizes based on the customer-provided runtime parameter value(s).

A new database scoped configuration option DOP_FEEDBACK automatically adjusts degree of parallelism for repeating queries to optimize for workloads where inefficient parallelism can cause performance issues. Similar to optimizations in Azure SQL Database. Requires the Query Store to be enabled and in "Read write" mode.

Identifies and corrects suboptimal query execution plans for repeating queries, when these issues are caused by incorrect estimation model assumptions. Requires the Query Store to be enabled and in "Read write" mode.

Uses compilation replay to improve the compilation time for forced plan generation by pre-caching non-repeatable plan compilation steps. Learn more in Optimized plan forcing with Query Store.

Integrated setup experience for the Azure extension for SQL Server

Install the Azure extension for SQL Server at setup. Required for Azure integration features.

Use SQL Server Configuration Manager to manage Azure extension for SQL Server service. Required to create Azure Arc-enabled SQL Server instance, and for other Azure connected features.

During setup, SQL Setup recommends a value for max server memory to align with documented recommendations. The underlying calculation is different in SQL Server 2022 to reflect recommended server memory configuration options.

There are several improvements to address persistent version store (PVS) storage and improve overall scalability. SQL Server 2022 implements a persistent version store cleaner thread per database instead of per instance and the memory footprint for PVS page tracker has been improved. There are also several ADR efficiency improvements, such as concurrency improvements that help the cleanup process to work more efficiently. ADR cleans pages that couldn't previously be cleaned due to locking.

Adds Transact-SQL support for freezing and thawing I/O without requiring a VDI client. Create a Transact-SQL snapshot backup.

In previous releases, shrinking databases and database files to reclaim space often leads to concurrency issues. SQL Server 2022 adds WAIT_AT_LOW_PRIORITY as an additional option for shrink operations (DBCC SHRINKDATABASE and DBCC SHRINKFILE). When you specify WAIT_AT_LOW_PRIORITY, new queries requiring Sch-S or Sch-M locks aren't blocked by the waiting shrink operation, until the shrink operation stops waiting and begins executing.

XML compression provides a method to compress off-row XML data for both XML columns and indexes, improving capacity requirements.

Avoid potential concurrency issues using asynchronous statistics update if you enable the ASYNC_STATS_UPDATE_WAIT_AT_LOW_PRIORITY database-scoped configuration.

SQL Server 2022 extends the BACKUP/RESTORE TO/FROM URL syntax by adding support for a new S3 connector using the REST API.

SQL Server Native Client (SNAC) has been removed

The SQL Server Native Client (often abbreviated SNAC) has been removed from SQL Server 2022 and SQL Server Management Studio 19 (SSMS). The SQL Server Native Client (SQLNCLI or SQLNCLI11) and the legacy Microsoft OLE DB Provider for SQL Server (SQLOLEDB) are not recommended for new development. Switch to the new Microsoft OLE DB Driver (MSOLEDBSQL) for SQL Server or the latest Microsoft ODBC Driver for SQL Server going forward.

Reduces the number of memcpy commands that need to be performed on modified data or index pages residing on PMEM devices. This enlightenment is now available for Window 2022 as well as Linux.

SQL Server 2022 leverages acceleration technologies from partners such as Intel to provide extended capabilities. At release, Intel® QuickAssist Technology (QAT) provides backup compression and hardware offloading.

SQL Server 2022 leverages new hardware capabilities, including the Advanced Vector Extension (AVX) 512 extension to improve batch mode operations.
