-------------------------------------------
Summary: Use integer constants for frequently used serde classes.
Key: HIVE-20363
URL: https://issues.apache.org/jira/browse/HIVE-20363
Project: Hive
Issue Type: Improvement
Components: Metastore, Standalone Metastore
Reporter: Anurag Mantripragada
Assignee: Anurag Mantripragada
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 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}
