Method and system for dynamic distributed data caching when a source of data is not available

摘要

A method and system for dynamic distributed data caching is presented. The method includes establishing a cache community of members for data storage. A request for data at a particular member of the cache community is generated. A cache location in the cache community where the data would be located is determined. A determination is made as to whether the data is stored at the cache location. The data is requested from a source of the data in response to the data not being cached at the cache location. A determination is made as to whether the source is currently unavailable to provide the data. The data is continuously requested from the source while waiting for the source to become available. The particular member is allowed to request other data while waiting for data to become available from the source.
