We live in a time where the rate with which data is being generated grows exponentially, and extracting useful information from all this data, becomes harder and harder, thus mandating efficient and scalable data analytics solutions. Oftentimes, the input data to analytics applications is in the form of massive, continuous data streams. Consider the example of the global stock markets: An interesting piece of information for traders, portfolio managers, and so on, are the correlation/dependence patterns between different market players (e.g., equities, indexes, etc.); yet, such patterns typically change very rapidly over time, and the information is only valuable if it becomes available in real time (e.g., for algorithmic trading). This implies that stock market data needs to be processed in a streaming fashion, typically focusing only on a sliding window} of recent readings (e.g., ``monitor all correlations during the last hour''). In addition, data stream processing solutions need to be scalable as there are thousands of market players, implying millions of possible correlation/dependence pairs that need to be tracked in real time. This thesis introduces efficient algorithms and architectures for tackling the problem of monitoring the pair-wise dependence among thousands of data streams, and introduces a generic stream processing framework, T-Storm, which can be used in order to easily and efficiently develop, scale-out, and deploy large-scale stream analytics applications.
