Esper

Compare

  Analyzed 1 day ago

Complex Event Processing, or CEP, is technology to process events and discover complex patterns among multiple streams of event data. ESP stands for Event Stream Processing and deals with the task of processing multiple streams of event data with the goal of identifying the meaningful events within ... [More] those streams, and deriving meaningful information from them. The Esper engine has been developed to address the requirements of applications that analyze and react to events. [Less]

Siddhi-CEP

Compare

  Analyzed about 19 hours ago

Siddhi is an open-source high performance complex event processing engine released under the Apache license 2.0. In a very high level view of Siddhi, the events come into the system in streams, and goes through several pre-set user queries. If the incoming events get matched with a given query, the ... [More] system triggers corresponding complex event to the output stream notifying the user of successful execution of the query. [Less]

openPDC

Compare

Claimed by Grid Protection Alliance (GPA) Analyzed about 10 hours ago

The open source phasor data concentrator is a system that is used to manage, process and respond to dynamic changes in fast moving streaming phasor data. More specifically, the openPDC can process any kind of data that can be described as “time-stamped measured values”. These measured values are ... [More] simply numeric quantities that have been acquired at a source device and are typically called points, signals, events, time-series values or measurements. When a value gets measured, an exact timestamp is taken, typically using a GPS-clock for accuracy – the value, along with its timestamp, is then streamed to the openPDC where it can be “time-aligned” with other incoming measurements so that an action can then be taken on a complete slice of data all measured at the exact same moment in time.
