------------------------------------------------------------
With tags and placement strategies, we can specify the location of schemas (databases), tables, and partitions when they are created. In this way, we have achieved fine-grained data placement.

In addition, not only can we specify the data placement at the time of creation by the create statement, but we can also modify the placement position of the data object through the alter statement, but since this operation causes data to move, it cannot be done during peak business hours.
