Providing data values using asynchronous operations and querying a plurality of servers

A computer program product for a processing system comprised of a first server to provide data values, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code including computer instructions, wherein a processor of the first server, responsive to executing the computer instructions, performs operations in the processing system comprising:

• maintaining a cache of objects communicatively coupled with the first server;
• executing an asynchronous computation to determine the value of a first object;
• returning a value of the first object from the cache of objects, in response to a request for the first object occurring before the asynchronous computation has determined the value of the first object;
• and
• returning a value of the first object determined by the asynchronous computation, in response to a request for the first object occurring after the asynchronous computation has determined the value of the first object, wherein the asynchronous computation determines the value of the first object by querying at least one additional server, wherein the at least one additional server comprises a plurality of servers including a second server and a third server, and the asynchronous computation receives different values of the first object from the second server and the third server, and wherein the asynchronous computation determines the value of the first object based on the different values of the first object received from the second server and the third server.

A processing system comprising:

• a first server including memory and a network interface device for communicating with one or more networks, at least one processor, communicatively coupled with the memory and the network interface device, and
• wherein the at least one processor, responsive to executing computer instructions, performs operations comprising:
• maintaining a cache of objects communicatively coupled with the first server;
• executing an asynchronous computation to determine the value of a first object;
• returning a value of the first object from the cache of objects, in response to a request for the first object occurring before the asynchronous computation has determined the value of the first object;
• and
• returning a value of the first object determined by the asynchronous computation, in response to a request for the first object occurring after the asynchronous computation has determined the value of the first object, wherein the asynchronous computation determines the value of the first object by querying at least one additional server, wherein the at least one additional server comprises a plurality of servers including a second server and a third server, and the asynchronous computation receives different values of the first object from the second server and the third server, and wherein the asynchronous computation determines the value of the first object based on the different values of the first object received from the second server and the third server.
