High Performance Tiled Map Service
Submitted by Shubham Bansal (@shubham-bansal) on Monday, 15 June 2015
To introduce the service behind the housing map interface and discuss the technical challenges and performance bottlenecks faced while developing the tiling map service.
Tiling service is the key service behind our map interface. It is responsible for smooth user interactions in dense inventory areas and, scaling our map interface. Our TMS(Tile Map service) faces the challenge of generating decluttered markers at real time for an unrestricted combination of filters and a rapidly changing inventory. The large number of filters restricts precomputation of tiles and frequent changes in inventory make it necessary to use a sophisticated caching mechanism. These conditions also make it impossible to have a client side overlay over Google Maps.
In this talk we’ll discuss the conditions that lead to creation of a dedicated maps service. We’ll also discuss the principal components of tiling service, such as, caching strategies, decluttering logic, real time image encoding techniques and the challenges we faced during their implementation.
There are no requirements for this session.
