Bases: ExtendedResolverProps

(experimental) Additional property for an AppSync resolver for GraphQL API reference.

Parameters:

  • field_name (str) – (experimental) name of the GraphQL field in the given type this resolver is attached to.

  • type_name (str) – (experimental) name of the GraphQL type this resolver is attached to.

  • caching_config (Union[CachingConfig, Dict[str, Any], None]) – (experimental) The caching configuration for this resolver. Default: - No caching configuration

  • pipeline_config (Optional[Sequence[IAppsyncFunction]]) – (experimental) configuration of the pipeline resolver. Default: - no pipeline resolver configuration An empty array | undefined sets resolver to be of kind, unit

  • request_mapping_template (Optional[MappingTemplate]) – (experimental) The request mapping template for this resolver. Default: - No mapping template

  • response_mapping_template (Optional[MappingTemplate]) – (experimental) The response mapping template for this resolver. Default: - No mapping template

  • data_source (Optional[BaseDataSource]) – (experimental) The data source this resolver is using. Default: - No datasource

  • api (IGraphqlApi) – (experimental) The API this resolver is attached to.
