Is it possible to get just a count of the no of columns in a row, in efficient manner ?

[Ertio Lew]

Can I get just a count of the no of columns in a row without
deserializing all columns in row? Or should the usage of a counter
column be preferred that maintains the no of columns currently present
in the row, for the situations when the total count value is most
frequently used than reading the actual columns ?

No.

Yes, you should use a counter instead if you are counting the length of
non-tiny rows very frequently.
