I haven't fully thought this out yet, but it strikes me that with an AWS SDK, Rust would be an ideal language for high performance Lambda functions. * No JVM/Interpreter memory overhead * No garbage collection (I know this is controversial) * Compiled binaries with low startup time * High performance (assuming you write it well..) * Aware of multi-core systems * Good networking capabilities Currently if you want really high performance on Lambda with a SDK for AWS services, you have to go Java and all that comes with it, or launch Go or C++ binaries via a nodejs process.
