When passing UpdateResolverRequest as input to an Aws::Client method, you can use a vanilla Hash:

{
  api_id: "String",   type_name: "ResourceName",   field_name: "ResourceName",   data_source_name: "ResourceName",
  request_mapping_template: "MappingTemplate",
  response_mapping_template: "MappingTemplate",
  kind: "UNIT",   pipeline_config: {
    functions: ["String"],
  },
  sync_config: {
    conflict_handler: "OPTIMISTIC_CONCURRENCY",     conflict_detection: "VERSION",     lambda_conflict_handler_config: {
      lambda_conflict_handler_arn: "String",
    },
  },
  caching_config: {
    ttl: 1,
    caching_keys: ["String"],
  },
}

• #api_id ⇒ String

  The API ID.

• #caching_config ⇒ Types::CachingConfig

  The caching configuration for the resolver.

• #data_source_name ⇒ String

  The new data source name.

• #field_name ⇒ String

  The new field name.

• #kind ⇒ String

  The resolver type.

• #pipeline_config ⇒ Types::PipelineConfig

  The PipelineConfig.

• #request_mapping_template ⇒ String

  The new request mapping template.

• #response_mapping_template ⇒ String

  The new response mapping template.

• #sync_config ⇒ Types::SyncConfig

  The SyncConfig for a resolver attached to a versioned datasource.

• #type_name ⇒ String

  The new type name.

The new data source name.

The resolver type.

• UNIT: A UNIT resolver type. A UNIT resolver is the default resolver type. A UNIT resolver enables you to execute a GraphQL query against a single data source.

• PIPELINE: A PIPELINE resolver type. A PIPELINE resolver enables you to execute a series of Function in a serial manner. You can use a pipeline resolver to execute a GraphQL query against multiple data sources.

  Possible values:

  • UNIT
  • PIPELINE

The new request mapping template.

A resolver uses a request mapping template to convert a GraphQL expression into a format that a data source can understand. Mapping templates are written in Apache Velocity Template Language (VTL).

VTL request mapping templates are optional when using a Lambda data source. For all other data sources, VTL request and response mapping templates are required.

The new response mapping template.

The SyncConfig for a resolver attached to a versioned datasource.
