Answer: Create a LSI
Create an LSI LSI stands for Local Secondary Index. Some applications only need to query data using the base table's primary key; however, there may be situations where an alternate sort key would be helpful. To give your application a choice of sort keys, you can create one or more local secondary indexes on a table and issue Query or Scan requests against these indexes.
