[jira] [Created] (HIVE-28684) There is no need to modify the properties of historical partitions when adding new fields and cascade=false

FangBO created HIVE-28684:
-----------------------------

             Summary: There is no need to modify the properties of historical partitions when adding new fields and cascade=false
                 Key: HIVE-28684
                 URL: https://issues.apache.org/jira/browse/HIVE-28684
             Project: Hive
          Issue Type: Improvement
    Affects Versions: 3.0.0
            Reporter: FangBO


We have a table which partition number is about 300,000. When we add column for the table without cascade, the ddl operation will increase the pressure of the metadata database.

 

We find HIVE-18138 will update all historical partition's properties. Actually, if we add new columns and cascade=false, there is no need to update historical partition's properties.
