> the describe of KeyValue:
> ...
>  * HBase applications and users should use the Cell interface and avoid directly using KeyValue and
>  * member functions not defined in Cell.
> ...
> for example,the use case of ColumnRangeFilter:
> ...
> ResultScanner rs = t.getScanner(scan);
> for (Result r = rs.next(); r != null; r = rs.next()) {
>  for (KeyValue kv : r.raw()) {
>  // each kv represents a column
>  }
> }
> ...
