* When making a table that can't be added right now, a Local secondary index must be created.
* You should therefore try specifying the two following parameters later on when you establish a local secondary index.
* The characteristic about which indexing and query processing are done is known as an indexed sort key.
* Attributes that can be directly copied into the school serves index are known as projected attributes. The local secondary index only contains primary keys and secondary keys when projected attributes are absent.
