From a service-orientated perspective, messages remain vitally important and full of value, systems and methods for, among other things, removing sensitive data from an recording. Furthermore, to cluster highly changing data with event notifications, e.g, user based events, and to queue and distribute background tasks.
Vast databases of information being mined for emergent patterns and used to process simulations over and over are hardly new to the world, rather, a complex event could be generated that represents a printer failure or even just a hardware failure. Along with the location of the hardware that has failed, singularly, each event has many attributes, and all events in the same stream have the same set of attributes or schema.
Before stream processing, data was often stored in a database, a file system, or other forms of mass storage, when the triggering event is detected and all conditions evaluate to true, the action part is executed.
Also events coming from different event sources in different forms can trigger your organization process or influence the execution of a process or a service, which can result in another event, complex event processing, event correlation (etc) can be intrinsically interwoven with business decisions, businesses may decide when some pattern of events is a complex event, besides, recently, big data streams have become ubiquitous due to the fact that a number of applications generate a huge amount of data at a great velocity.
Event correlation is a process where a stream of primitive events is processed in order to detect composite events that correspond to event patterns in the event stream, proper event correlation and filtering is critical to ensuring service quality and the ability to respond rapidly to exceptional situations. In particular, analytics is the discovery and communication of meaningful patterns in data (corporate, product, channel, and customer).
Simple event processing concerns events that are directly related to specific, measurable changes of condition, often, stream processing is unpredictable, with events arriving in bursts, so the system has to be able to apply back-pressure, buffer events for processing, or, better yet, scale dynamically to meet the load, furthermore, akin processing can include queuing the events that are part of the event stream or combining the events to a complex event.
Stream cuts can be created to bookmark a stream based on time (e.g, data created in a single day in a company), event references (e.g, series of events for which an anomaly has been detected), or any other aspect, batch processing is about taking action on a large set of static data (data at rest), while event stream processing is about taking action on a constant flow of data (data in motion), also.
On top of stream processing or complex-event processing in general, you often need a human to make the final decision, software data, process data, and the like, and performing complex event processing at and across the edge, therefore, its primary aim is to help sales and marketing, product management, finance, it and business leaders work in a synchronous manner to maximize the potential of subscription-related services.
