Namit Jain commented on HIVE-625:
---------------------------------
It is difficult to generalize - think about a script operator which consumes
most of the rows, similar to a filter.
We can make it configurable, but I am not sure what the default should be. In
most of the cases, BinarySortableSerDe should be better.
> Use of BinarySortableSerDe for serialization of the value between map and
> reduce boundary

> We currently use LazySimpleSerDe which serializes double to text format.
> Before we have LazyBinarySerDe, we should switch to BinarySortableSerDe
> because that's still much faster than LazySimpleSerDe.
