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. Finagle is written in Scala, but provides both Scala and Java idiomatic APIs. Finagle is a protocol-agnostic, asynchronous RPC system for the JVM that makes it easy to build robust clients and servers in Java, Scala, or any JVM-hosted language. We set out to develop a single implementation of the basic components of network servers and clients that could be used for all of our protocols. Finagle is a protocol-agnostic, asynchronous Remote Procedure Call (RPC) system for the Java Virtual Machine (JVM) that makes it easy to build robust clients and servers in Java, Scala, or any JVM-hosted language.
Features
- Finagle supports a wide variety of request/response- oriented RPC protocols
- Finagle clients and servers expose statistics for monitoring and diagnostics
- Finagle uses a clean, simple, and safe concurrent programming model, based on Futures
- Most of Finagle’s code is protocol agnostic, simplifying the implementation of new protocols
- Finagle is an extensible RPC system for the JVM, used to construct high-concurrency servers
- This project is used in production at Twitter (and many other organizations), and is being actively developed and maintained
