Highlights and new features
1. Performance Improvements:
SQL Server 2025 is centred on performance enhancements on different workloads.
Intelligent Query Processing (IQP): IQP has been growing with new capabilities that automatically optimize query processing plans. This makes use of adaptive memory grant feedback, whereby memory allocation dynamically adapts to real query demand, and better estimation of cardinality of complicated queries.
Accelerated Database Recovery (ADR) enhancements: ADR, originally introduced in an earlier version, reduces the impacts of lengthy transactions by enabling near instantaneous database recovery. ADR is further improved in SQL Server 2025, in performance and scalability.
In-Memory OLTP Optimizations: In-Memory OLTP, which scales high-throughput transaction processing, is further optimized in SQL Server 2025. This will improve support of larger memory configurations, and performance improvement on specific workloads.
2. Security Enhancements:
Security is of the highest priority in SQL Server 2025.
Ledger for SQL Server: Ledger also offers tamper-evident data verification. It cryptographically proves data integrity and so it is less difficult to detect malicious modification. This is very applicable to uses that may need high levels of data trusts and compliance.
Secure Enclaves Enhancements: Always Encrypted helps to protect sensitive data by encrypting it in the client, so the database server never possesses access to plaintext data. SQL Server 2025 also includes a performance boost and more flexible query capabilities to Always Encrypted.
Enhanced Auditing: SQL Server 2025 will have enhanced auditing that gives you finer control over what is audited and more extensive reporting.
3. Data Analytics and Management:
SQL Server 2025 provides new capabilities in handling and analysis of data.
SQL Server 2025 provides more functions and features in time series data analysis, allowing easier analysis of trends and patterns over time.
Graph Database: The graph database features in SQL Server are extended with new querying and analysis capabilities of the relationships among data points.
Data Virtualization Enhancements: Data virtualization enables you to interrogate information on multiple sources without having to physically transfer data. The data virtualization in SQL Server 2025 is optimized, and more data can be linked to it.
4. Development Environment
The development environment of SQL Server 2025 changes.
T-SQL Extensions: SQL Server 2025 has new T-SQL syntax and functions that make creating advanced queries and doing data manipulation tasks easier.
SQL Server 2025 will have new functions and features in the processing of JSON data, which should make it easier to store it and query JSON documents.
Future: Integration with Azure Services: SQL Server 2025 will further integrate with Azures services so that deployment and management of SQL Server in the cloud is simpler.
Upgrade Considerations
SQL Server 2025 upgrade may need a thorough planning and testing.
Compatibility Testing: Before upgrading, it is important to carry out a serious compatibility testing to assure that your current applications and databases would work well.
Upgrade Advisor: The SQL Server Upgrade Advisor can be used to assist in identifying potential problems and provide some guidance on how to address these new problems.
The rollback plan should be there as a contingency in case the upgrade goes sour.
Conclusion
SQL Server 2025 Release Candidate is a powerful piece of new functions and improvements. By critically assessing such capabilities and laying a plan of upgrading to SQL Server 2025, you will be able to take advantage of the full potential of this powerful tool and improve the performance, security, and reveal new insights into your data.
