Hey there! Got a noob Q.. Is there an example code (Py) that someone can point me too .. that does ingestion - both metadata and then the actual data as well using datahub apis. e.g. Say from a snowflake datasource i want to identify all tables that have say "member_id" column in it and then pull the actual raw data from those tables and dump it in a local/serverside db/file etc. Is this a typical usecase or the usecase of actually pulling raw data is not supported? thx !
