Method and system for caching real-time data

摘要

A system and method for storing data representing a multidimensional entity using corresponding dimensions for the data, storing a further dimension for the data, the further dimension being a modification timestamp indicating a time when the data was modified, receiving a request for the data representing the multi-dimensional entity, the request including a request timestamp indicating a further time when a previous request for the data representing the multi-dimensional entity was received and transmitting the data only when the modification timestamp is later than the request timestamp.

1. A method, comprising:
using a caching function to allow a client to notify a server of data that is currently cached at the client and new data that is needed by the client; storing the data representing a geographic entity and a corresponding modification timestamp indicating a time when the data was most recently modified; receiving a request for the data representing the geographic entity, the request including a request timestamp indicating a further time when a most recent previous request for the data was made; and transmitting the data only when the modification timestamp is more recent than the request timestamp.
