             Summary: Add new LazyBinary SerDe for faster writes
                 Key: HIVE-17611
                 URL: https://issues.apache.org/jira/browse/HIVE-17611
             Project: Hive
          Issue Type: Improvement
          Components: Serializers/Deserializers
            Reporter: Jason Dere
            Assignee: Jason Dere


LazyBinarySerDe.serialize() ends up making getCategory()/getPrimitiveCategory() 
calls for every column of every row. Tried some simple tests to eliminate these 
calls for the non-vectorized version, this looks like it speeds up the writes 
by ~3x.
Adding a LazyBinarySerDe2 class with this new implementation.
