Product status updates - sync

the idea is to update status for various products.I have two functions (onStatusChange, updateProductStatus)onStatusChange gets called on a status change for a certain product.The update function is async and it updates the status of product.​Then multiple updates for same product should be sequential.​How can I achieve this? Any ideas with the algorithm and data structure would of a great help.
