Class LambdaRuntime

java.lang.Object
com.codename1.backend.LambdaRuntime
public final class LambdaRuntime extends Object

The AWS Lambda custom-runtime loop.

Why this is the first server-side target: the Lambda Runtime API is a CLIENT-side HTTP/1.1 poll over plaintext loopback, and the host serialises invocations one per instance. So a runtime needs no listening socket, no event loop, no TLS and no virtual threads - exactly the four things a general server runtime needs and this VM does not yet have. What it does need is fast start-up, which is what a translated binary is good at.

Protocol (2018-06-01): long-poll GET .../invocation/next, which blocks until an invocation arrives and returns the payload plus a Lambda-Runtime-Aws-Request-Id header; then POST the result to .../invocation/{id}/response, or the failure to .../invocation/{id}/error.
