------------------------------------------
Summary: Database should have creation time
Key: HIVE-21077
URL: https://issues.apache.org/jira/browse/HIVE-21077
Project: Hive
Issue Type: Improvement
Components: Standalone Metastore
Reporter: Vihang Karajgaonkar
Assignee: Vihang Karajgaonkar
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 no the server if the dbName
is same. Without object ids creationTimeStamp is the only way currently to
identify uniquely a instance of metastore object. It would be good to have
Database creation time as well.
