But you can change the key definition to get semi-sorted behavior.  This
would give you some parallelism while still grouping recent keys into the
same pages.

Doing an on-the-fly key transition is pretty hairy, but doable.

Accessing older data just requires knowing the cutoff date and doing one
encoding or the other.
