The Netty redesign of riemann-java-client made it possible to expose an end-to-end asynchronous API for writes, which has a dramatic improvement on messages with a small number of events. By introducing a small queue of pipelined write promises, riemann-clojure-client can now push 65K events per second, as individual messages, over a single TCP socket. Works out to about 120 mbps of sustained traffic.

I’ve had two observations floating around in my head, looking for a way to connect with each other.

Many “architecture patterns” are scar tissue around the absence of higher-level language features.
