Extend metastore schema to store column properties
--------------------------------------------------
Key: HIVE-1789
URL: https://issues.apache.org/jira/browse/HIVE-1789
Project: Hive
Issue Type: Bug
Components: Metastore
Reporter: Ashish Thusoo
Assignee: Ashish Thusoo
A common use case in data warehousing deployments is to set column level
policies, e.g. certain columns in the table need to be retained for a longer
period than others. Without column level properties, you would have to encode
this information into table properties and maintain those properties as columns
change. A better solution is to have properties associated with columns.
