Lesson: Design Considerations of Yelp
Hi Ravish.
A quadtree is used in Yelp’s design to optimize searching for nearby places. By dynamically splitting segments into a quadtree structure based on the number of places, it improves search performance by limiting the number of places in each segment to 500.
The quadtree also helps connect neighboring segments, making it easier to search within a given radius by traversing linked segments.
In summary, the quadtree optimizes searching for nearby places by dynamically segmenting data and linking neighboring segments. This improves the scalability and performance of searches.
