Firestore’s batched writes are preferred in scenarios where multiple write operations need to be executed as a single atomic unit. For instance, consider an e-commerce application that needs to update inventory and process user orders simultaneously. If the order processing fails, it is crucial to revert the inventory updates to maintain data consistency. This can be achieved using Firestore’s batched writes which ensures all or none of the operations succeed. In contrast, single writes would not provide this level of transactional integrity, potentially leading to inconsistent data states if one operation fails while others succeed.
