External Memory Stream Sampling
Summary: Introduce the external memory stream (EMS) model for I/O-aware sampling when samples exceed RAM. Provide EMS-specific techniques and matching upper/lower bounds for with- and without-replacement sampling on append-only and time-based sliding windows, exposing hardness separations from RAM.
