Reactor offers implementations for generating infinite sequences of data. At the same time, it offers an API for publishing a single data entry. This is suited to the request-response model. Each API offers methods aimed at handling the specific data cardinality.
Rather than waiting for the entire data collection to arrive, subscribers to each data stream can process items as they arrive. This yields optimized data processing, in terms of space and time. The memory requirement is limited to a subset of items arriving at the same time, rather than the entire collection. In terms of time, results start to arrive as soon as the first element is received, rather than waiting for the entire dataset.
