I'm doing a test to use GCP Data Catalog (DataPlex) to document tables from Big Query. I'm doing in a dev project, in the future, I'd like transfer data that I documented (description of columns, overview of table) from dev project to prod project? Is it possible?
https://github.com/mesmacosta/datacatalog-util is an export/import utility that lets you achieve what I believe you are looking for, provided that you use tags to store these descriptions?
