Abstract
As disclosed herein, a system for conducting mapping and reducing operations includes a shared storage subsystem that is connected to one or more mapping servers and one or more reducing servers via a high-speed data link and communication protocol. Each mapping server receives a multitude of data records, aggregates the data records having a particular value, and sorts and stores the resulting aggregated data records on the shared storage subsystem. Each reducing server accesses the shared storage subsystem and accumulates information on the aggregated data records for a particular common value. In many instances, the access rates to the shared storage subsystem achieved by the mapping servers and the reducing servers approach that of accessing a local attached storage device. A computer program product and method corresponding to the system for conducting mapping and reducing operations are also disclosed herein.
