Availability - SQL Server 2022

SQL Server 2022 includes several new and improved features related to availability that help organizations to ensure the availability and protection of their data. Here's a detailed explanation of some of these features:

Link to Azure SQL Managed Instance: SQL Server 2022 introduces the ability to link an on-premises SQL Server instance to an Azure SQL Managed Instance. This makes it easier for organizations to move their data to the cloud and take advantage of the high availability and disaster recovery features provided by Azure SQL Managed Instance. For example, an organization can use the link to Azure SQL Managed Instance to ensure that its data is protected and available even in the event of a disaster.

Contained Availability Group: SQL Server 2022 introduces the ability to create a contained availability group, which allows organizations to create an availability group that does not rely on a shared cluster or shared storage. This makes it easier for organizations to ensure the availability of their data in multi-node scenarios. For example, an organization can use a contained availability group to ensure that its data remains available even if one or more nodes in the availability group fail.

Distributed Availability Group: SQL Server 2022 introduces the ability to create a distributed availability group, which allows organizations to create an availability group that spans multiple instances of SQL Server, both on-premises and in the cloud. This makes it easier for organizations to ensure the availability of their data in multi-node and multi-location scenarios. For example, an organization can use a distributed availability group to ensure that its data remains available even if one or more instances of SQL Server fail.

Improved Backup Metadata: SQL Server 2022 introduces improved backup metadata, which makes it easier for organizations to manage their backups and ensure the availability and protection of their data. For example, an organization can use the improved backup metadata to ensure that its backups are up-to-date and can be used to recover its data in the event of a disaster.

These new and improved features in SQL Server 2022 related to availability help organizations to ensure the availability and protection of their data. By leveraging these features, organizations can minimize downtime and ensure that their data is protected, even in the most adverse conditions.

How data is replicated from the Primary Replica to the Secondary Replica in a SQL Server Always On Availability Group

Image
When it comes to high availability in SQL Server, Always On Availability Groups offer a robust solution for ensuring data resilience and fault tolerance. At the heart of this technology is a sophisticated log-based replication mechanism distinct from traditional database mirroring or snapshot replication. Let’s walk through exactly how data moves from the Primary Replica to the Secondary Replica, step by step. High-Level Process Flow  Primary Replica → Log Generation → Log Transport → Log Reception → Redo → Acknowledgement. Step-by-Step Explanation 1. Client Writes Data to Primary Replica * A client application sends a transaction (e.g., INSERT, UPDATE) to the Primary Replica. * SQL Server writes this transaction to the transaction log of the primary database. * This log write is made to the log buffer and flushed to disk before the transaction is considered committed. 2. Log Block is Captured by the Always On Transport Manager * The HADR_LOG_SEND_MANAGER process monitors the trans...

Standard Developer and Enterprise Developer edition in SQL Server 2025

Image
Standard Developer and Enterprise Developer edition in SQL Server 2025 In SQL Server 2025, two new Developer editions are introduced: Standard Developer and Enterprise Developer. These editions are designed for development and testing purposes and are licensed for free. The Standard Developer edition includes all the features of the Standard edition, while the Enterprise Developer edition offers the complete functionality of the Enterprise edition.  Standard Developer Edition Free licensing: It can be used without incurring any licensing costs.  Matches Standard edition: It mirrors the features and capabilities of the SQL Server Standard edition.  Ideal for teams: It's particularly valuable for teams whose production workloads run on Standard edition.  Narrowing the gap: It helps to minimize the difference between development and production environments, especially for applications that rely on Standard or Web/Express editions.  Improves code predictability: It ...

Accelerated Database Recovery (ADR) in SQL Server

Image
Accelerated Database Recovery (ADR) is one of the most transformative features in recent SQL Server releases, and with SQL Server 2025, it’s more powerful and flexible than ever. ADR is a SQL Server feature designed to drastically improve database availability by reengineering the recovery process. Traditional recovery could take a long time, especially with long-running transactions, because SQL Server had to scan the transaction log from the oldest uncommitted transaction. ADR changes this by introducing a new architecture that makes recovery and rollback nearly instantaneous, regardless of transaction length or database activity. Key Benefits : Fast and consistent recovery : Recovery time is no longer affected by the number or size of active transactions. Instantaneous rollback : Even very long-running transactions can be rolled back instantly. Aggressive log truncation : The transaction log is truncated more aggressively, preventing log growth even with active long transactions. H...
