Apama Correlator
Real-time Control. Real-time Response.
The Progress® Apama® Correlator provides sophisticated event pattern-matching logic to turn rapidly moving data into meaningful business events. The Correlator executes Apama applications developed within Apama Studio to track inbound event streams and "listen" for event patterns that match defined conditions. These conditions can include both time- and location-based events, thus offering solutions not possible with other technologies.
Through its patented HyperTree architecture, the Correlator can monitor tens of thousands of events per second - with thousands of application scenarios - and respond in sub-millisecond time. This high-performance, memory-based execution far surpasses the data and logic constrained capabilities of traditional rules engines.
Multiple Correlators can monitor and execute rules in parallel to provide unmatched scalability that can adapt as business needs change. The Correlators can concurrently monitor events from different sources, providing exponentially more sophisticated analysis. Should an event, an event sequence, or an event pattern - in a single event stream or across several - match a scenario, it provides visibility or action as defined by scenario rules.
Correlators do not execute in the procedural (sequential) manner of traditional imperative programs. Apama applications should be considered modular compositions that segment the event monitoring, analysis and action stages into logically-related, but independent, segments. This segmentation is particularly valuable in addressing the requirements inherent in event processing applications where there may be hundreds of thousands of monitor operations executing simultaneously.
The Apama Correlator is uniquely appropriate for business event processing applications like algorithmic trading, location-based services, and managing inventory in motion, where events correlated across multiple, and often disparate systems, are the keys to competitive advantage.
