Summary: Deduplicate SerDe Info
Key: HIVE-25779
URL: https://issues.apache.org/jira/browse/HIVE-25779
Project: Hive
Issue Type: New Feature
Components: Standalone Metastore
Reporter: Yu-Wen Lai
Assignee: Yu-Wen Lai
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.
