Answer 1

The ProjectionExpression parameter is used in a GetItem call to specify the attributes that you want to return from the item.

Step-by-step explanation:

The ProjectionExpression parameter is used in a GetItem call to specify the attributes that you want to return from the item. By using this parameter, you can select only the specific attributes that are of interest to you, rather than retrieving the entire item. This can help optimize the performance and reduce the amount of data transmitted.
