Unbounded data and continuous processing

Datasets can be classified as unbounded or bounded. Bounded data is finite; it has a beginning and an end. Unbounded data is an ever-growing, essentially infinite data  set. The distinction is independent of how the data is processed. Often, unbounded data is equated to stream processing and bounded data to batch processing, but this is starting to change. We will see how state-of-the-art stream processors, such as Apache Apex, can be used to (and are very capable of) processing both unbounded and bounded data, and there is no need for a batch processing system just because the data set happens to be finite.
