GraalVM requires all the code available in order to produce a native image. You’d need to pre-bind the topology you want Flink to run into the native image. More fun, you’ll actually need two images, one for the job manager and one for the task manager. And you’ll need to convince GraalVM that the entry-point is your topology needs reflection support enabled... plus whatever other classes use reflection in Flink. Sounds rather complex to me. If native images are what is important to you, there seemed to be a strong contender in the Rust language community, didn’t provide as strong management as Flink, and you’d probably have more work managing things like checkpointing, but if native code is important that’s where I’d be looking.
