Say we have an existing e-commerce feature which is the typical backend of an e-commerce website and we want to add a reviews feature which will be handled by a separate microservice. I'd like you to construct this review feature please. The criteria known after probing: You are allowed to use existing solutions (e.g. Akamai for CDN, Amazon S3 for Object Storage, Kafka for Message Brokering) The backend has a relational database. You can either use this or create another database, but please state why you decided against using the existing one. 50 requests per minute Unknown users per day The review will consist of text, multiple images and stars (rating system from 1-5). Average stars can be FLOAT, but what users input will be INTEGER. The E-Commerce website has a products page that can display multiple products and its average star rating. For this, create an api for an existing feature called 'products' which will be able to fetch all data from the 'products' table along with its average stars. You may choose to modify the existing products table, but please state the reason as opposed to creating a new table and have the product key as a foreign key to that table. Users will be able to Create, Read, Update but not Delete Reviews. Create APIs for these. Make sure that whenever a user creates or updates their reviews, the average stars are recalculated. You will have to create: A diagram of how the existing components will be connected to the new feature that you created. APIs for each feature that requires an API. For each API, write the correct request method which fits that API, the SQL query which corresponds to the API, the HTTP Response Code befitting that API, and request body template for that API.
