> 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.
