Abstract
In a data processing system, a received data stream comprises a plurality of tuples having respective key values. The received data stream is separated into portions that are delivered to respective ones of a first set of servers in a manner that permits different tuples having the same key value to be processed by different servers of the first set. For each distinct key value, each of at least a subset of the servers of the first set maintains a corresponding partial key result based on one or more of the tuples having that key value that are received by that server. The partial key results are periodically delivered from the servers of the first set to servers of a second set of servers in a manner that ensures that different partial key results having the same key value are processed by the same server of the second set.
