Re: Emissary, a fast open-source Java messaging library
#2Emissary is a simple-to-use, no dependency, yet BLAZING FAST messaging library for decoupling messages (requests and events) and message handlers.
Emissary aims to take advantage of the simplicity of using the annotations for handlers (e.g. @RequestHandler/@EventHandler) without the drawbacks of reflection (slow).
What differentiates Emissary from other messaging/dispatch libraries? It takes advantage of java.lang.invoke.LambdaMetafactory to avoid the cost of invoking methods reflectively. This results in performance close to directly invoking the request handler and event handler methods.
~ 1000% more throughput compared to other similar libraries (Spring's ApplicationEventPublisher, Pipelinr, EventBus) ~ 90% faster compared to other similar libraries (Spring's ApplicationEventPublisher, Pipelinr, EventBus)

Assuming that you are the author of Emissary, this could be a Show HN, I think.

I always enjoy how low-tech this website is. Not necessarily great UX, but it's quaint.

#6I'm a big fan of Guava's EventBus. Easy to implement and straightforward to understand. This library does seem to require more setup and I don't see the immediate advantages, also why does it require an instanceProvider? I don't understand what that does.
