Design of Yelp
Connect a spatial index to authoritative business records. The index finds candidate place IDs; the record store supplies current details, and an aggregator applies the query’s filters and ranking rule.
Following the requirements and estimations from the previous lesson, we will now focus on the API design, storage schema, and system building blocks.
API design
This section outlines the API endpoints for the system.
Search
The search function locates places based on categories (e.g., “cafes”):
search(category, user_location, radius)| Parameter | Description |
|---|---|
category | This is the type of search the user makes, for example, a search for restaurants, cinemas, cafes, and so on. |
user_location | This contains the location of the user who’s searching with Yelp. |
radius | This is the specified radius where the user is trying to find the required category. |
Return a paginated list of matching places within the requested radius, including name, address, category, rating, and a thumbnail reference. Specify coordinate format, distance units, maximum radius, and deterministic ordering so a query can be repeated or continued.
