>
> Upon ObjectStore initialization, we need to determine which type of
> underlying db is by asking the connection the product name. It's a waste of
> time and resource to do this, as long as we don't change the database
> connection information, the db type shouldn't be changed, sometimes
> retrieving the connection for the secondary connection pool(which size is 2)
> could be time cost, which can lead to HiveMetastoreClient spending much time
> to connect to the Metastore.
