Finagle: A Network Stack for the JVM
Marius A. Eriksen

We share our experience building and deploying Finagle, a library for building robust and highly performant asynchronous RPC servers and clients. Finagle is built on top of Netty and uses futures as a unifying abstraction in order to provide an intuitive and powerful API on top of asynchronous dispatching.
Finagle supports a variety of RPC styles, including request-response, streaming, and pipelining. It is protocol agnostic, and we have implemented codecs for the core protocols at Twitter. We will talk about:

• the design & technical underpinnings of Finagle
• the use of futures and channels
• integration with Java projects
• its use at Twitter
• developer experience
