We should support various metrics to help inform datafusion's explain analyze:

Scan - How many bytes were read from disk? How many rows were produced?
Take - How many rows were taken?
Vector search - How many vectors were compared? How many rows matched the prefilter?
Scalar index search - How many rows matched the prefilter exactly? at most?

And so on
