Avalanche service is a class library for processing requests and results, for mitigating consumers and producers.
There is separation of request, handling and result. This allows separation of aspect, inversion of control, expandability, plugin architecture, reusability, and decorability.
Service converts a request into a response by sending a query to be processed by a stack of handlers.
// Create handler Action<IQuery<string, Type>> handler = q => q.Response.SetValue(Type.GetType(q.Request)); // Create service IService service = Services.Create(handler); // Create request string request = "System.String"; // Issue request Type? response = service.Get<string, Type>(request);

When getting a result that is already in cache, the result is provided at 200ns and with zero heap allocation.
When constructing a new result, there is total overhead of 400ns for one handler, and very low heap allocation.
When using async call model for getting a cached result is 450ns.
When using async call model for creating a new result with one handlers is 1350ns
