METHOD AND APPARATUS FOR PROVIDING TILES OF DYNAMIC CONTENT

Some techniques for providing tiles of dynamic content include a service that determines a generation time and update time in response to receiving a request for a particular tile, and that returns the particular tile. The generation time is when the particular tile of dynamic content was most recently generated based on particular vector data associated with the particular tile. The update time is when the particular vector data was most recently updated. The particular tile is generated based on the particular vector data in response to determining that the generation time is not later than the update time. Some techniques include a client that receives data that indicates an estimated time to complete generation of a tile in response to sending a first request for the tile. A second request for the tile is sent at a time based at least in part on the estimated time.
