                 .name("id")
                 .type(AttributeType.STRING)
                 .build())
         .build();
 DynamoDbDataSource demoDS = api.addDynamoDbDataSource("demoDataSource", demoTable);
 // Resolver for the Query "getDemos" that scans the DynamoDb table and returns the entire list.
 demoDS.createResolver(BaseResolverProps.builder()
         .typeName("Query")
         .fieldName("getDemos")
         .requestMappingTemplate(MappingTemplate.dynamoDbScanTable())
         .responseMappingTemplate(MappingTemplate.dynamoDbResultList())
         .build());
 // Resolver for the Mutation "addDemo" that puts the item into the DynamoDb table.
 demoDS.createResolver(BaseResolverProps.builder()
         .typeName("Mutation")
         .fieldName("addDemo")
         .requestMappingTemplate(MappingTemplate.dynamoDbPutItem(PrimaryKey.partition("id").auto(), Values.projecting("input")))
         .responseMappingTemplate(MappingTemplate.dynamoDbResultItem())
