MAINTAINING PORTLET DATA CURRENCY WHILE MINIMIZING LATENCY

摘要

Providing data to portlets can include a step of registering a plurality of portlets to determine a type of data required by the portlets. The registering can establish a portlet context for handling future data requests for the portlets. A type of information associated with one of the portlets can be determined. A data acquisition process can be initialized to obtain the determined type of information from a data source. A data request can be received for data of the determined type from the associated portlet. Data can be acquired from the data source using the initialized process. The data request can be responded to using the acquired data. In one embodiment, the acquisition of data from the source and the updating of the portlets can occur asynchronously, where a cache is used to temporarily store data acquired from the data source that is used to update the portlets.
