|
|
- I/O operations regarding Infinity, a persistent storage cluster based on HDFS.
|
|
|
Creation, usage and deletion of private computing clusters based on MapReduce and SQL-like querying systems such as Hive or Pig.

|
The CEP GE analyses event data in real-time, generates immediate insight and enables instant response to changing conditions. While standard reactive applications are based on reactions to single events, the CEP GE reacts to situations rather than to single events. A situation is a condition that is based on a series of events that have occurred within a dynamic time window called processing context. Situations include composite events (e.g., sequence), counting operators on events (e.g., aggregation) and absence operators. The IBM Proactive Technology Online (Proton) is an implementation of the FiWARE CEP (Complex Event Processing) GE. The IBM Proactive Technology Online is a scalable integrated platform to support the development, deployment, and maintenance of event-driven applications. The IBM Proactive Technology Online authoring tool allows the definition of CEP applications using a web user interface. The The IBM Proactive Technology Online engine is a runtime tool that receives information on the occurrence of events from event producers, detects situations, and reports the detected situations to external consumers.
