The Scan operator in one next() call delivers vectors from all the relevant _columns_ (we don't have BATs anymore). Naturally, the scans are buffered so the I/O granularity is much larger than a vector size.
The X100 paper mentions that the engine is based on top of MonetDB. Are you still using BATs at the lowest level or did you move to a different way of storing data? Could you elaborate on the new disk structure if you are no longer using BATs? Thanks, Joel -- http://wagerlabs.com/uptick
