Exploring the New Features of SQL Server 2025 Preview
In November 2024, Microsoft made waves by unveiling a private preview of SQL Server 2025, and the excitement continued with the public preview that launched in May 2025. With development and testing still underway, Microsoft has introduced a host of new features for this upcoming release, underscoring its commitment to enhancing database performance and security.
Support for Ubuntu 24.04
One of the significant updates is the compatibility of SQL Server 2025 Release Candidate 0 (RC0) with Ubuntu 24.04. This addition provides developers using Ubuntu an opportunity to experiment with the Enterprise Evaluation Edition of SQL Server 2025 in their development and testing environments. However, Microsoft advises against using this version in live production settings. Instead, it recommends that developers stick to SQL Server 2022 on Ubuntu 22.04 or Red Hat Enterprise Linux 9 for production deployments.
Installation Guides and Resources
For those eager to dive into the new features, Microsoft has compiled a helpful quickstart guide for installing the SQL Server 2025 preview on Ubuntu 24.04. Additionally, a detailed guide for deployment on systems operating under Windows Subsystem for Linux 2 (WSL2) can be found here.
Enhanced Security Features
Another important aspect of the SQL Server 2025 preview is that it has Transport Layer Security (TLS) 1.3 enabled by default. This enhancement provides improved security for data in transit, reflecting the increasing importance of data protection in today’s digital landscape.
Features Tailored for AI Workloads
SQL Server 2025 represents a pivotal advancement for businesses that leverage AI. Key features include native support for vector embeddings, enhancing performance for AI-related workloads. The accompanying. NET and JDBC drivers have similarly adapted, achieving impressive benchmarks: up to 50 times faster reads, 3.3 times faster writes, and a remarkable 19 times increase in bulk copy operations. Furthermore, the introduction of an AI-integrated database engine, enhanced JSON support, and the Copilot feature in SQL Server Management Studio (SSMS) makes this release particularly attractive.
Innovative Optimizations
The new Optimized Locking mechanism in SQL Server 2025 is designed to reduce memory consumption related to locks and minimize transaction blocking. This is accomplished through innovative features like Transaction ID (TID) Locking and Lock After Qualification (LAQ), which enhance overall database efficiency.
Looking Ahead
While an exact release date for SQL Server 2025 has yet to be disclosed, it is highly anticipated that it will become available in 2025. As developers and businesses continue to adapt their strategies to incorporate AI and advanced data processing features, SQL Server 2025 is set to be a game changer in the database management landscape.
