Even though we have column descriptions in the CREATE queries for tables in wmf_product, some tables were not created using those queries but were created by various members of the team under their personal databases and then transferred under wmf_product at a later date. As a result, those tables do not have documentation in Hive Metastore.
This has an unfortunate side effect of those fields not having descriptions in our data catalog MVP (e.g. editor_month; CREATE query)
We would need to alter them (see https://www.tutorialspoint.com/hive/hive_alter_table.htm)
