Dynamic Data Masking Demo | Snowflake Inc.

If there is dynamic masking on the columns that is role based , will it have any impact on the etl jobs ?

Have ever dealt with regex for example how to detect phone numbers or email address on a string and if so do you examples that you can share of the regex utilized?

I dont see role policyadmin , when would it be available for existing Snowflake Users, can you please mention?

Nice definition. One question if my masking column is getting joined to other table should it work?
