Complex Event Processing
Back to glossaryWhat is Complex Event Processing [CEP]?
Complex event processing [CEP] also known as event, stream or event stream processing is the use of technology for querying data before storing it within a database or, in some cases, without it ever being stored. Complex event processing is an organizational tool that helps to aggregate a lot of different information and that identifies and analyzes cause-and-effect relationships among events in real time. CEP matches continuously incoming events against a pattern and provides insight into what is happening. and allows you to proactively take effective actions.
Major Application Areas for Complex Event Processing [CEP]:
- Business Activity Monitoring aims at identifying problems and opportunities in early stages by monitoring business processes and other critical resources.
- Sensor Networks that are used for monitoring of industrial facilities. These are usually derived from raw numerical measurements [e.g., temperature, smoke].
- Market data such as stock or commodity prices; they need to be derived from several events and their relationships through CEP.
The Most Common Tools Used for Complex Event Processing Are:
- Apache Spark Streaming used by Databricks
- Apache Flink used by data Artisans
- Apache Samza used by LinkedIn
- Apache Storm used by Twitter
- Hadoop/MapReduce.
- Amazon Kinesis Analytics
- Microsoft Azure Stream Analytics, Stream Insight
- Fujitsu Software Interstage Big Data Complex Event Processing Server
- IBM Streams, Operational Decision Manager [ODM]
- Oracle Stream Analytics and Stream Explore
