Hi all, I was reading this old blog post from OmniSci <https://www.omnisci.com/blog/fast-and-flexible-query-analysis-at-mapd-with-apache-calcite-2>and they mention that to use Calcite-generated plans in their C++ library, they serialized the relational algebra output by Calcite into JSON. I'd like to do something like this for a project but I can't seem to find any good documentation of this. I found this page in the docs <https://calcite.apache.org/docs/model.html> about the model, but what I am looking for hopefully is a function that I can pass the root of a Calcite plan and get a JSONified serialization. Does this exist?
Thanks, Lana
