> Caching in {{IInputPartition}} is currently entirely dependent on the implementation
of the {{IInputPartition}}. We should modify/expand {{IInputPartition}} such that the data
loading component is fully separate from the caching component. An idea is to instead provide
only a single concrete {{IInputPartition}} implementation (while deprecating the old implementations)
and use the composition model, complete with an {{IDataLoader}} which fetches data back in
a {{Stream}}, and an {{IDataCache}}, which allows caching at granular levels.
