Reaqtor

Reaqtor provides a set of libraries that are essential to building distributed, reliable, stateful, and highly scalable reactive solutions. It roughly consists of the following core components:

• Client-side abstractions used to build client libraries used to create and delete subscriptions, manage streams, publish events, etc.
• A query engine that provides reliable execution of Reaqtive queries, including state persistence through checkpointing.
• Facilities for reliable event flows across services, using sequence numbers and with replay capabilities.
• Libraries to aid with hosting of query engines in services.
