A company needs to share its product catalog data with one of its partners. The product catalog data is stored in two database tables: PRODUCT_CATEGORY, and PRODUCT_DETAILS. Both tables can be joined by the PRODUCT_ID column. Data access should be governed, and only the partner should have access to the records.
The partner is not a Snowflake customer. The partner uses Amazon S3 for cloud storage.
Which design will be the MOST cost-effective and secure, while using the required Snowflake features?
