Abstract: Certain examples described herein provide a data processing system and method adapted for event processing. These examples provide for distribution of data processing operations between server computing devices. In one case, a plurality of processing stages are implemented using computing instances on the server computing devices. In this case, the computing instances are assigned to the server computing devices in order to perform at least one data processing operation in parallel. Certain examples described herein then provide for the distribution of data between computing instances such that parallelism is maintained for data processing operations. In certain cases, a composite key is used. In this case, a composite key value is computed for a set of data fields associated with a data item to be processed. This key value is computed based on a data processing operation to be performed. The key value is used to route the data item to an associated computing instance implementing the data processing operation.
