How to make local secondary indexes?

A Local secondary index should be made at the hour of making a table that can't be included as of now.

In this way, when you make a local secondary index, have a go at determining the accompanying two parameters.

Indexed Sort Key: The trait on which ordering and questioning are performed.

Projected Attributes: It is the rundown of properties from the table that can legitimately be replicated into the nearby auxiliary list. Without anticipated traits, the local secondary index contains just essential keys and optional keys.
