[jira] [Updated] (HIVE-21077) Database should have creation time
[ 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.
