Abstract

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.

Claims

1. A method comprising facilitating access, including granting access rights, to an interface to allow access to a service via a network, the service configured to:

in response to receiving a request for a particular tile of dynamic content, determine a generation time, wherein the generation time is a time when the particular tile of dynamic content was most recently generated based on particular vector data associated with the particular tile;

determine an update time, wherein the update time is a time when the particular vector data was most recently updated;

determine whether the generation time is later than the update time; and

cause the particular tile to be generated based on the particular vector data in response to determining that the generation time is not later than the update time, by determining whether data indicating the particular tile is already included in a queue that indicates any tiles to be generated from associated vector data if data indicating the particular tile is not already included in the queue, then cause data indicating the particular tile to be added to the queue; and

if data indicating the particular tile is already included in the queue, then cause data not to be added the queue; and

the method further comprises returning the particular tile of dynamic content via the network.

2. A method of claim 1, the service further configured to retrieve the particular tile from cache without causing the particular tile to be generated based on the particular vector data, if the generation time is later than the update time.

3. A method of claim 1, wherein to cause the particular tile to be generated further comprises to:

store the particular tile into cache; and

set the generation time associated with the particular tile to a value that indicates when the particular tile was generated.

12. A method of claim 11, further comprising causing an operation to be performed during a time interval between receiving the data that indicates the estimated time and causing the second request to be sent, wherein the operation is independent of causing the first request to be sent and causing the second request to be sent and determining whether a response is received to the first request or the second request.

13. An apparatus comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

determine an update time, wherein the update time is a time when the particular vector data was most recently updated;

determine whether the generation time is later than the update time;

cause the particular tile to be generated based on the particular vector data in response to determining that the generation time is not later than the update time; and

cause the particular tile of dynamic content to be returned;

wherein causing the particular tile to be generated based on the particular vector data further comprises;

determining whether data indicating the particular tile is already included in a queue that indicates any tiles to be generated from associated vector data;

if data indicating the particular tile is not already included in the queue, then causing data indicating the particular tile to be added to the queue; and

if data indicating the particular tile is already included in the queue, then causing data not to be added the queue.

14. An apparatus of claim 13, wherein the apparatus is further caused, at least in part, to retrieve the particular tile from cache without causing the particular tile to be generated based on the particular vector data, if the generation time is later than the update time.
