Reaqtor evolves Reactive Extensions (Rx) by adding state & durability primitives to enable long running "Rx as a Service" queries, for processing live or historic data streams.

Real world deployments of Reaqtor handle billions of standing stateful queries, processing thousands of events per second. It powers services across Bing, MSN, and M365.

It's just .NET, so you can host it on a Raspberry Pi, in a .NET Interactive Notebook, a Console App, or build your own durable cloud-native hosting environment if you need planet-scale, ultra-high density reactive processing.
