You need to design the primary key for DynamoDB based on three attributes. What do you do?

  • Designate all three fields as the primary key.
  •  Concatenate all three fields into one new field, then designate that new field as the primary key.
  •  Designate two fields of the three fields as the primary key.
  •  Concatenate two fields into one new field, then designate that new field and the remaining field as the primary key.
