The "feature" product functionality in WooCommerce 3+:

Since version 3, WooCommerce generates a featured term (name and slug) located in wp_terms table, which custom taxonomy is product_visibility in wp_term_taxonomy table.

The wp_term_relationships table make the link between:

• the "featured" products IDs through the object_id key
• the ID for product_visibility taxonomy through term_taxonomy_id key

The wp_term_taxonomy table make the link with the term featured through its term_id key.

It works jut like a post term.

The product_visibility taxonomy also handle those terms (functionalities):

• exclude-from-search (product visibility option)
• exclude-from-catalog (product visibility option)
• outofstock (stock status)
• rated-1 to rated-5 (product rating)
