> Serde libraries are stored as fully qualified class names which are long
> strings, we can get improvements in I/O and storage if we store integer
> constants for frequently used serde classes in the backend DB.
> For example:
> {code:java}
> org.apache.hadoop.hive.serde2.avro.AvroSerDe"---> 1
> parquet.hive.serde.ParquetHiveSerDe" ---> 2
> ...{code}
