問題文
A provider wants two partners to run joint analysis on overlapping customer records without either side seeing the other's raw rows. Which Snowflake capability is designed for that?
選択肢
- A listing on the marketplace with an aggregation policy attached.
- A direct share of the raw tables to each partner, combined with masking policies on the identifying columns, because the masks keep each partner from seeing the other side's identities while the join still works on the underlying values.
- Data clean rooms, where the analyses that a collaborator may run are defined by the data owner and only aggregated results come back.
- A reader account for each partner, so that neither partner has an account of their own.
