Description

Right now, there are number of things that make it difficult to use Calcite with GraalVM native compilation.

There are several reasons that supporting this kind of compilation could be beneficial:

• Enable use of Calcite as a Lambda with minimal startup-time
• Create a Calcite shared library that can be easily embedded in other languages

Initially, I would focus this work on core parsing and query planning.

This work was inspired by work on https://substrait.io

Let's use this ticket to track improvements that can be done to enable this.
