Introducing Microsoft’s Platform for Complex Event Processing

While typical relational database applications are query-driven, event-driven applications have become increasingly important. Event-driven applications are characterized by high event data rates, continuous queries, and millisecond latency requirements that make it impractical to persist the data in a relational database for processing. These requirements are shared by vertical markets such as manufacturing, oil and gas, utilities, financial services, health care, web analytics, and IT and data center monitoring. Event-driven applications use complex event processing (CEP) technology with the goal of identifying meaningful patterns, relationships and data abstractions from among seemingly unrelated events and trigger immediate response actions.

Tracking All the Queries

I have 3 instances of a brand new long running query that are executing on a SQL Server 2025 instance. Query store is enabled. One of the queries is killed by the administrator, one is cancelled by the user. The other runs to completion. How many rows are in Query Store for this query?
