Shuaifeng Zhou commented on HBASE-13122:
----------------------------------------
NEXT_ROW can work is because there is regionscanner and store scanner, next_row
affect store scanner.
When one storescanner switch to next row, the region scanner switch to the next
storescanner, the second store scanner will continue check the current row.
That why the change can be more efficiency.
> Improve efficiency for return codes of some filters

> ColumnRangeFilter:
> when minColumnInclusive is false, it means all the cells at the current
> row&column not fit the condition, so it should skip to next column, return
> code should be NEXT_COL, not SKIP.
> FamilyFilter is the similar sitution.
> Currently, SKIP will not causing error, but not efficent.
