add a Java wrapper for datafusion #1108

Description

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

A challenge to add a Java wrapper for datafusion, so that we can leverage Rust's speed and memory management and also Java's eco-system.

Describe the solution you'd like
A clear and concise description of what you want to happen.

Unlike Python where we have maturin - an easy to use binding to Rust, I'm trying to use JNI in this case but that requires handling memory on/off heap. One way to achieve this is to leverage Arrow's IPC between Java and Rust.

Describe alternatives you've considered
