 DDBTable:
    Type: AWS::DynamoDB::Table
    Properties:
      TableName: YOUR_EXISTING_TABLE_NAME
      AttributeDefinitions: #List out all existing cols here
        -
          AttributeName: "ColX" # hash key
          AttributeType: "S"
        -
          AttributeName: "ColY" # range key
          AttributeType: "S"
        -
          AttributeName: "ColZ" # used for your Global Secondary Index 
          AttributeType: "S"

      KeySchema: # List out your main Hash & Range Key
        -
          AttributeName: "ColX"
          KeyType: "HASH"
        -
          AttributeName: "ColY"
          KeyType: "RANGE"

      GlobalSecondaryIndexes: #  new Global Secondary Index

        KeySchema:
        - AttributeName: ColZ #different than your main table Hash Key
