As of today, you can create 20 global secondary indexes per Amazon DynamoDB table in AWS GovCloud (US). If you need more than 20 global secondary indexes, you can request an increase.

In addition, you can now have 100 projected index attributes for both global secondary indexes and local secondary indexes when you specify the ProjectionType of INCLUDE. You still can specify the ProjectionType of ALL to project all attributes from the source table, even if the table has more than 100 attributes.
