> HIVE-21077 adds CREATION_TIME to Database, and it will be available in the metastore notifications. Hence,
>  # For CREATE_DATABASE events, we should compare the creationTime of the Database in catalog with the Database in the event to make sure we are ignoring the event only if catalog has the latest Database object.
>  # For DROP_DATABASE events, we should check that creation time of database in the notification and the catalog match to make sure that we are removing the correct database object.
