Shopper - Listing the top 10 best selling products

Don wants to know what are the top 10 best selling products on the dimestore website.

Thanks to N1QL, we can now easily query the data in Couchbase to produce that list.

    SELECT product.name, sum(items.count) as unitsSold 
    FROM purchases unnest purchases.lineItems as items 
    JOIN product key items.product 
    GROUP BY product 
    ORDER BY unitsSold desc limit 10
