How to Screen a Data Stream - Quality-Driven Load Shedding in Sensor Data Streams
As most data stream sources exhibit bursty data rates, data stream management systems must recurrently cope with load spikes that exceed the average workload to a considerable degree. To guarantee low-latency processing results, load has to be shed from the stream, when data rates overstress system resources. There exist numerous load shedding strategies to delete excess data. However, the cons...
متن کاملA Framework For Supporting Load Shedding in Data Stream Management Systems
The arrival rate of tuples in a data stream can be unpredictable and bursty. Many stream-based applications have Quality of Service (QoS) requirements that need to be satisfied by the underlying stream processing system. In order to avoid violating predefined QoS requirements during temporary overload periods, a load shedding strategy is necessary and critical for a data stream management syste...
متن کاملMining Data Stream for Load Shedding
Data stream is continuous flow of data, which necessitates load shedding for data stream processing system. Here we study overload handling for frequent pattern mining indata streams. Here in this paper load shedding use frequent pattern matching algorithm i.e priority, transaction and attribute in overload situation. The heavy workload or continues stream of the mining algorithm lies mostly in...
متن کاملOn Load Shedding in Complex Event Processing
Complex Event Processing (CEP) is a stream processing model that focuses on detecting event patterns in continuous event streams. While the CEP model has gained popularity in the research communities and commercial technologies, the problem of gracefully degrading performance under heavy load in the presence of resource constraints, or load shedding, has been largely overlooked. CEP is similar ...
متن کاملContent-based Load Shedding in Multimedia Data Stream Management System
Overload management has become very important in public safety systems that analyse high performance multimedia data streams, especially in the case of detection of terrorist and criminal dangers. Efficient overload management improves the accuracy of automatic identification of persons suspected of terrorist or criminal activity without requiring interaction with them. We argue that in order t...
