The AWS::AppSync::Resolver resource 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 .

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 .

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.appsync.*;
