Event-Stream Processing

What Does Event-Stream Processing Mean?

Event-stream processing (ESP) is a group of technologies engineered to facilitate the generation of event-driven information systems. ESP is comprised of basic elements like event visualization, event databases, event-driven middleware and event processing languages (also known as complex event processing (CEP).


Although ESP and CEP are slightly different, they are often used interchangeably.

Techopedia Explains Event-Stream Processing

ESP processes data from various sources in an attempt to identify meaning within complex patterns of events. In order to do this, ESP uses techniques such as:

  • Detecting complex patterns among a group of events
  • Event correlation and abstraction
  • Determining the hierarchy of events
  • Determining the relationships between events, which may include causality, membership and timing.

ESP is used to conduct algorithmic securities trading, to detect fraud and to aid in the provision of location-based telecommunication services.
