Fivetran currently has the option to automatically include new schemas and tables in the sync, however when selecting specific columns to sync, new columns are still added by default.
I have a use case where a source table has 500+ columns, more are created on a regular basis, and I only want to sync 13 of them - no more and no less. When a new column is created in the source, Fivetran automatically adds it to the sync.
This isn't the worst problem (and much better than the alternative of not syncing when you want it to!), however it would be ideal to have the option to sync or not sync new columns in a given table.
