We are thrilled to announce that the performance enhancement features previously available as a limited public preview for Azure SQL Database Hyperscale are now Generally Available (GA)! These enhancements have been rigorously tested and embraced by many customers, who have already realized significant benefits. Let’s dive into the details and hear how these innovations are reshaping database performance and scalability.

Enhanced Performance Features Now GA

Increased Transaction Log Generation Rate to 150 MiB/s

The transaction log generation rate for Azure SQL Database Hyperscale, now at 150 MiB/s, delivers faster data processing and better handling of write-intensive workloads. Customers who participated in the public preview reported remarkable results, including significantly faster data loads into the database. One key area of impact was the ability to smoothly transition to Hyperscale from other databases, enabling a more efficient transition while maintaining performance standards.

Continuous Priming for Optimal Performance

Continuous priming optimizes performance during failovers by ensuring that secondary replicas are primed with the “hot pages” of the primary replica. This innovation has drastically reduced read latencies for secondary replicas. For example, internal customer Azure DevOps has enabled continuous priming and observed substantial benefits in their RBPEX utilization, leading to enhanced operational efficiency.

Customer Success Stories

Throughout the public preview, customers reported faster bulk data imports, real-time data ingestion, and smoother transition to Hyperscale, thanks to the increased transaction log generation rate. Similarly, continuous priming decreased read latencies for secondary replicas, benefiting read-heavy workloads and failovers. Azure DevOps serves as a prime example of success, leveraging continuous priming to optimize RBPEX usage effectively.

What does this mean for you

These features, now available for all customers, mark a significant step forward in database technology. Whether you’re considering transitioning to Hyperscale or looking to optimize your current setup, these enhancements offer powerful tools to meet your growing data and performance needs. The feedback from our customers during the public preview has been invaluable, and we are excited to see how these features will continue to drive success across diverse use cases.

Next Steps

We invite you to explore these new capabilities and fully leverage what Azure SQL Database Hyperscale has to offer. Please note that these features are being rolled out region by region and will be available in all regions by the end of June. As always, we are here to support you every step of the way.
