Estimated rows at or above which representation: "auto" selects columnar.
Set at the SDK's bounded-local materialization ceiling
(MAX_LOCAL_MATERIALIZATION_ROWS): below it a result is small enough that
feature objects stay affordable, at or above it the per-row object cost is
exactly the problem a columnar batch exists to remove.
