Resource governor - a new beginning
Executive summary In addition to increased CPU and memory limits, we are making another change to benefit customers using the SQL Server Standard edition. Starting with SQL Server 2025, resource governor, previously an Enterprise edition feature, is also available in the Standard edition. A powerful tool Resource governor has been a part of SQL Server for more than 15 years. It’s a powerful, full-featured tool that improves reliability when multiple applications or users share resources on the same SQL Server instance. We rely on Resource Governor to isolate workloads on our SQL Server instances by controlling CPU and memory usage. It helps us ensure that the core of our trading systems remains stable and runs with predictable performance, even when other parts of the systems share the same servers. - Ola Hallengren, Chief Data Platforms Engineer at Saxo Bank and a Data Platform MVP Yet when we ask customers if they use resource governor, a frequent answer is "We can't. We are on Standard edition." Indeed, ever since its initial release, resource governor has been an Enterprise-only feature. That made it less known and less commonly used than it deserves. We heard and acted on your feedback. Starting with SQL Server 2025, resource governor is available in both Standard and Enterprise editions, with identical capabilities. This includes the respective Developer editions as well. In Azure SQL Managed Instance, resource governor is already available in all service tiers. What can it do? Here are just some of the things you can accomplish using resource governor: Limit or reserve CPU bandwidth and IOPS for a workload. Limit the size of query memory grants or reserve memory for query processing. Limit the total number of running requests (queries) for a workload. Abort query batches that exceed a specified amount of CPU time. Set a hard cap on the maximum degree of parallelism (MAXDOP) for queries. (New in SQL Server 2025) Limit the amount of tempdb space a workload can use (blog | doc). Whether you are on Standard or Enterprise edition, if you haven't used resource governor yet, see what it can do for you. To help you learn, we have a new step-by-step guide with best practices and examples, from simple to more advanced. There is also a separate guide focusing on the new tempdb space governance feature. Conclusion With this change, customers on Standard edition get a powerful enterprise-grade tool to control resource contention and improve reliability of their SQL Server environments. We encourage you to learn more about resource governor to understand the full range of its capabilities. Have questions or feedback?

Let’s make resource governor a standard (😊) tool in your toolset!Introducing optimized locking v2
Executive summary New improvements in optimized locking further reduce the overhead of locks in the MSSQL database engine. For many transactions, row and page locks aren’t taken at all while still retaining ACID transaction semantics. The improvements require no changes in customer workloads or configuration and are a part of optimized locking in SQL Server 2025, Azure SQL Database, SQL database in Fabric, and Azure SQL Managed Instance. Optimized locking recap Optimized locking was originally released in Azure SQL Database in 2023. The feature has two components: Transaction ID (TID) locking Lock After Qualification (LAQ) With TID locking, while individual row and page locks are still taken, they are not held until the end of transaction because the transaction remains protected by a single TID lock. Concurrency is improved because lock escalation is much less likely to occur. Memory usage is also improved because locks are released soon after they are acquired. With LAQ, locks are taken just before a qualified row is modified. This optimistic locking strategy improves concurrency because locks aren’t held while qualifying rows for modification. At Infios, we are very excited about several new features in SQL Server 2025 and the vast amount of opportunities for performance improvements. We are most excited about the optimized locking feature and how that can drastically help reduce locking across our customers and all their unique workloads. - Tim Radney, SaaS Operations Manager at Infios and a Data Platform MVP Improvements In recent months, we have made two improvements that make a database more lock-free and make the benefits of optimized locking available to more workloads: Skip index locks (SIL) Query plan LAQ feedback persistence These improvements are in effect if read committed snapshot isolation (RCSI) is enabled for the database, which is the default in Azure SQL Database and SQL database in Fabric. To gain the most benefit from optimized locking, enable RCSI. Skip index locks With TID locking, lock escalation typically doesn’t occur because locks are released fast enough to avoid crossing the escalation threshold. A large transaction that modifies many rows without lock escalation must acquire and release many locks. These locks don’t consume a lot of memory because they are released quickly. However, each lock acquisition and release requires a call into the Lock Manager component within the engine. Cumulatively for a large transaction, the overhead of these calls might be significant. The SIL improvement reduces this overhead by skipping row and page locks when they are not required to guarantee ACID semantics. When transactions are protected by TID locks, and when RCSI and LAQ are used, an exclusive lock on a modified row is only necessary if there might be other queries accessing the row and expecting it to be stable. Examples of such queries are those that use the Repeatable Read or Serializable isolation levels, or the corresponding locking hints. We call such queries Row Locking Queries, or RLQ. In the SIL improvement, the engine was modified to maintain a special No-RLQ bit for each page in the buffer pool. This bit indicates the absence of RLQ queries accessing any row on the page. When this bit is set, a DML transaction can skip taking row and page locks and instead modify a row with just an exclusive page latch. Based on the Azure SQL Database telemetry, RLQ queries are uncommon in workloads using RCSI or snapshot isolation transactions. Telemetry also tells us that at least half of all DML queries, on average, use LAQ. This indicates that many workloads can benefit from the SIL improvement. Query plan LAQ feedback persistence LAQ uses an optimistic locking strategy. Locks are taken only after a row is qualified for modification, not while qualifying the row. This means that statement processing might need to be internally restarted if another transaction modified the row after it was read but before it was modified by the current transaction. If statement restarts happen frequently, the use of LAQ might introduce a noticeable overhead because the work to process the DML statement needs to be redone. The engine tracks the potentially wasted work and statement restarts. In the original version of optimized locking, this data is aggregated across all statements and tracked in memory at the database level. If the potentially wasted work or statement restarts exceed thresholds, LAQ is disabled for the entire database, and re-enabled if the potentially wasted work and restarts go below the thresholds. With the new improvement, in addition to tracking at the database level, the engine also tracks LAQ feedback at the query plan level and persists it in Query Store. If thresholds are exceeded for a particular query plan, LAQ is disabled only for that plan rather than for the entire database. The rest of the workload still benefits from LAQ. Skipping locks – a demo To demonstrate the SIL improvement, we used SQL Server 2025 to run a workload that executes an UPDATE statement 100 times in a loop. Each statement updates a random number of rows in a table with a clustered index. We used an extended events session with a histogram target to collect the lock_acquired event. Each histogram bucket counts the number of acquired locks for a specific resource type, including KEY and PAGE. Here are the results: For this execution of the demo, 99.6% of key locks and 79% of page locks are skipped. For details, see the Appendix later in this post. Improvement at the Azure scale To zoom out and demonstrate the SIL improvement broadly, the next chart summarizes telemetry data for about 25K databases in Azure SQL Database. The chart shows the ratio of the total skipped to total acquired locks by index type. Broadly, the improvement is most pronounced for nonclustered indexes, where 81% of locks are skipped. Conclusion Improvements in optimized locking show our continuing investment in this core database engine feature. We fine-tuned optimized locking beyond an already successful v1 release and further reduced the overhead of locks. For more information about these two improvements, see Skip index locks and LAQ heuristics. As of this writing, the improvements are enabled in SQL Server 2025 and for most databases in Azure SQL Database and SQL database in Fabric. The rollout to the remainder of the Azure SQL fleet including Azure SQL Managed Instance (with the always-up-to-date and SQL Server 2025 update policy) is in progress. Appendix Here are the T-SQL scripts to demonstrate SIL in action.

Today, most of the world’s data still remains untapped, sitting in databases, documents, and systems across organizations. Enterprises are racing to unlock this data’s value by building the next wave of generative AI applications—solutions that can answer questions, summarize documents, and drive smarter decisions. At the heart of these innovations are retrieval-augmented generation (RAG) pipelines, which enable users to interactively engage with large amount of data that continuously evolves. Yet, as promising as RAG pipelines are, enterprises face real challenges in making them work at scale. Handling both structured and unstructured data, processing massive volumes efficiently, and ensuring privacy and security are just a few hurdles. This is where the integration between SQL Server 2025 and NVIDIA Nemotron RAG models, deployed as NVIDIA NIM microservices, comes in, offering a new approach that streamlines AI deployment and delivers enterprise-grade performance—whether you’re running workloads in the cloud or on-premises. “As AI becomes core to every enterprise, organizations need efficient and compliant ways to bring intelligence to their data,” said Joey Conway, Senior Director of Generative AI software at NVIDIA. “With SQL Server 2025’s built-in AI and NVIDIA Nemotron RAG, deployed as NIM microservices, enterprises can deploy and run AI models close to their data on premises or in the cloud without complex integration, accelerating innovation while maintaining data sovereignty and control.” Overcoming the complexity of generating embeddings at scale Customer challenge Building responsive AI applications using RAG requires converting SQL data into vector embeddings—a process that feeds huge amounts of text through complex neural networks. This is inherently parallel and compute-intensive, often creating performance bottlenecks that prevent real-time data indexing. The result? Slow applications and poor user experiences. Moreover, enterprises need flexibility.
