chunhui shen commented on HBASE-9769:
-------------------------------------

Move the logic of above patch to Scan class, is it also OK?

It means adding the ExplicitColumnsFilter in Scan.java when setting the 
attribute "SCAN-SMALL-ROWS"

In addition, I'm worry the data correctness if Scan already has complex filters.

> Improve performance of a Scanner with explicit column list when rows are 
> small/medium size
