Question: Can a DynamoDB range key be a GSI key?
Answered by Rafal Wilinski
Answer
Yes, a DynamoDB range key can also be used as a GSI (global secondary index).It is common to use the same attribute as the range key and the GSI key. When you create a GSI, you can specify the range key attribute as the key to be indexed. This allows you to perform query operations on the range key attribute using the GSI and query and scan operations on the primary key attribute using the table.
