SAP Sybase Event Stream Processor 5.1 SP04 provides the ability to automatically partition elements within an ESP project for parallel processing, allowing greater project scalability by eliminating bottlenecks.
Automatic partitioning is the creation of parallel instances of a given element and partitioning input data into these instances. Partitioning data this way results in higher performance as the workload is split across the parallel instances. Use automatic partitioning to improve the performance of a given element and complex projects, which perform computationally expensive operations such as aggregation and joins.
Quickly and easily create parallel instances of a delta stream, stream, window, or module by using the PARTITION BY clause. You can use either ROUNDROBIN, HASH, or CUSTOM partitioning functions.
