> The simple describe table command without EXTENDED and FORMATTED (i.e.,
> DESCRIBE table_name) fetches all partitions when no partition is specified,
> although it does not display partition statistics in nature.
> The command should not fetch partitions since it can take a long time for a
> large amount of partitions.
> For instance, in our environment, the command takes around 8 seconds for a
> table with 8760 (24 * 365) partitions.
