I am working on a new Magento 2.1.4 projet. We have a single store. And we need to manage the inventory for a large amount of shops belonging to this store.
I was thinking about using the cataloginventory_stock tables. We did it on a Magento 1.x version. But since Magento 2, the unique index of the cataloginventory_stock_item table has changed. It is now on the product_id and website_id. Which allow only one line of stock per product and website. In version 1.x the unique index was on product_id and stock_id which would be more suitable.
Is this a bug that the stock_id disapeared from the cataloginventory_stock_item? Or is it something planned?
Thanks for your help
