Subject [jira] [Updated] (HIVE-21077) Database should have creation time
Date Fri, 28 Dec 2018 20:36:00 GMT

     [ https://issues.apache.org/jira/browse/HIVE-21077?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vihang Karajgaonkar updated HIVE-21077:
---------------------------------------
    Description: 
Currently, database do not have creation time like we have for tables and partitions.

{noformat}
// namespace for tables
struct Database {
  1: string name,
  2: string description,
  3: string locationUri,
  4: map<string, string> parameters, // properties associated with the database
  5: optional PrincipalPrivilegeSet privileges,
  6: optional string ownerName,
  7: optional PrincipalType ownerType,
  8: optional string catalogName
}
{noformat}

Currently, without creationTime there is no way to identify if the copy of Database which
a client has is the same as the one on the server if the name is same. Without object ids
creationTime value is the only way currently to identify uniquely a instance of metastore
object. It would be good to have Database creation time as well.
