Enterprise friends: what is snowflake and why did it have fine grained permissions for a whole company? I didn’t understand it from the snowflake website.

Snowflake is a Data Warehouse that is hosted in the cloud. The permission policies that you can define can become very complex - actually I find it's too complicated, I prefer BigQuery from GCP because of this reason.

When you have 10,000 users scattered across every continent your access control needs get complex.

ex: you don't want all users to be able to access finance's tables, else you might have folks trading stock on information they're not supposed to be privy to.
