Jacques Nadeau commented on ARROW-1710:
---------------------------------------
The consolidation doesn't inline the values. They are simply prepended. All
validity bits come before all data bytes. They are just in the same ArrowBuf
rather than maintaining two ArrowBufs. Normally we use different buffers to
support resizing only one. However, in the case of validity and data, both will
get resized at the same time depending on the values held.
