This talk mainly discusses the architecture we built to handle thousands of requests per minute for location-based restaurant campaigns in Foodpanda. The main problem is we need to show the restaurant campaigns based on customer location. Foodpanda (<a href="https://www.foodpanda.com" rel="nofollow" target="_blank">https://www.foodpanda.com</a>) serves customers in 11 Asia Pacific countries. Each country can have multiple campaigns where each campaign can have thousands of restaurants as part of it. Each vendor can have multiple delivery area polygons. For each request from the customer, we need to check if there are any campaigns belong to that customer and show it to them as fast as possible.
