Finagle is an extensible RPC system for the JVM, used to construct
high-concurrency servers. Finagle implements uniform client and server APIs for
several protocols, and is designed for high performance and concurrency. Most of
Finagle’s code is protocol agnostic, simplifying the implementation of new
protocols.
