Design Considerations of a Flexible Data Stream Processing Middleware
Techniques for efficient and distributed processing of huge, unbound data streams have made some impact in the database community. Distributed data stream processing systems have emerged providing a distributed environment to process these potentially unbound streams of data by a set of processing nodes. A wide range of real-time applications process stream-based data. Sensors and data sources, such as position data of moving objects, continuously produce data that is consumed by, e.g., location-aware applications. Depending on the domain of interest, the processing of such data often depends on domain-specific functionality.
