Explanation in CloudFormation Registry
The
AWS::AppSync::Resolverresource defines the logical GraphQL resolver that you attach to fields in a schema. Request and response templates for resolvers are written in Apache Velocity Template Language (VTL) format. For more information about resolvers, see Resolver Mapping Template Reference.Note When you submit an update, AWS CloudFormation updates resources based on differences between what you submit and the stack's current template. To cause this resource to be updated you must change a property value for this resource in the CloudFormation template. Changing the Amazon S3 file content without changing a property value will not result in an update operation. See Update Behaviors of Stack Resources in the AWS CloudFormation User Guide.
