Short-circuiting serialization
------------------------------
Key: HIVE-358
URL: https://issues.apache.org/jira/browse/HIVE-358
Project: Hadoop Hive
Issue Type: Improvement
Components: Serializers/Deserializers
Reporter: Zheng Shao
When a field from one table is going to be stored directly into a field of
another table, and both of the tables have the same serde configurations, we
don't need to deserialize the field and serialize the field again. This will
save substantial amount of CPU time if the field is big (e.g. map of array of
map, etc).
