With exponential growth in data generated from sensor data streams, search engines, spam filters, medical services, online analysis of financial data streams, and so forth, there is demand for fast monitoring and storage of huge amounts of data in real-time. Traditional technologies were not aimed to such fast streams of data. Usually they required data to be stored and indexed before it could be processed.
Stream computing was created to tackle those problems that require processing and classification of continuous, high volume of data streams. It is highly used on applications such as Twitter, Facebook, High Frequency Trading and so forth.
This subject will focus on the algorithms and data structures behind the analysis and management of streams. Theoretical underpinnings are emphasized, with implementation of some fundamental algorithms.
- Why stream processing is important
- Hash functions, probability, and fundamental data structures
- Data stream model
- Data stream algorithms: Sampling, sketching, distinct items, frequent items, frequency moments, etc.
- Data stream mining: clustering, histograms, query tracking
- Graph streams: connectivity, matchings, covers.
