Response Structure

• (dict) --

  • resolvers (list) --

    The Resolver objects.

    • (dict) --

      Describes a resolver.

      • typeName (string) --

        The resolver type name.

      • fieldName (string) --

        The resolver field name.

      • dataSourceName (string) --

        The resolver data source name.

      • resolverArn (string) --

        The resolver Amazon Resource Name (ARN).

      • requestMappingTemplate (string) --

        The request mapping template.

      • responseMappingTemplate (string) --

        The response mapping template.

      • kind (string) --

        The resolver type.

        • UNIT : A UNIT resolver type. A UNIT resolver is the default resolver type. You can use a UNIT resolver to run a GraphQL query against a single data source.
        • PIPELINE : A PIPELINE resolver type. You can use a PIPELINE resolver to invoke a series of Function objects in a serial manner. You can use a pipeline resolver to run a GraphQL query against multiple data sources.

      • pipelineConfig (dict) --

        The PipelineConfig .

        • functions (list) --

          A list of Function objects.

          • (string) --

      • syncConfig (dict) --

        The SyncConfig for a resolver attached to a versioned data source.

        • conflictHandler (string) --

          The Conflict Resolution strategy to perform in the event of a conflict.

          • OPTIMISTIC_CONCURRENCY : Resolve conflicts by rejecting mutations when versions don't match the latest version at the server.
          • AUTOMERGE : Resolve conflicts with the Automerge conflict resolution strategy.
          • LAMBDA : Resolve conflicts with an Lambda function supplied in the LambdaConflictHandlerConfig .

        • conflictDetection (string) --

          The Conflict Detection strategy to use.

          • VERSION : Detect conflicts based on object versions for this resolver.
          • NONE : Do not detect conflicts when invoking this resolver.

        • lambdaConflictHandlerConfig (dict) --

          The LambdaConflictHandlerConfig when configuring LAMBDA as the Conflict Handler.

          • lambdaConflictHandlerArn (string) --

            The Amazon Resource Name (ARN) for the Lambda function to use as the Conflict Handler.

      • cachingConfig (dict) --

        The caching configuration for the resolver.

        • ttl (integer) --

          The TTL in seconds for a resolver that has caching activated.

          Valid values are 1–3,600 seconds.

        • cachingKeys (list) --

          The caching keys for a resolver that has caching activated.

          Valid values are entries from the $context.arguments , $context.source , and $context.identity maps.

          • (string) --

      • maxBatchSize (integer) --

        The maximum batching size for a resolver.

      • runtime (dict) --

        Describes a runtime used by an Amazon Web Services AppSync pipeline resolver or Amazon Web Services AppSync function. Specifies the name and version of the runtime to use. Note that if a runtime is specified, code must also be specified.

        • name (string) --

          The name of the runtime to use. Currently, the only allowed value is APPSYNC_JS .

        • runtimeVersion (string) --

          The version of the runtime to use. Currently, the only allowed version is 1.0.0 .

      • code (string) --

        The resolver code that contains the request and response functions. When code is used, the runtime is required. The runtime value must be APPSYNC_JS .

  • nextToken (string) --

    An identifier to pass in the next request to this operation to return the next set of items in the list.
