> We can reuse serde info as how we reuse column descriptors. (HIVE-2246)
> Currently, each storage descriptor has a associated and exclusive serde info,
> but the partitions' serde infos are mostly just the same as the table's. By
> reusing the serde info, we can saving some database storage and possibly
> enhance the query performance from HMS to the backend database.
