Anurag Mantripragada updated HIVE-20363:
----------------------------------------
Description:
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}
