Options

--api-id (string)

The API ID.

--type-name (string)

The new type name.

--field-name (string)

The new field name.

--data-source-name (string)

The new data source name.

--request-mapping-template (string)

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 an Lambda data source. For all other data sources, VTL request and response mapping templates are required.

--response-mapping-template (string)

The new 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.

Possible values:

• UNIT
• PIPELINE

--pipeline-config (structure)

The PipelineConfig .

functions -> (list)

A list of Function objects.

(string)

Shorthand Syntax:

functions=string,string

JSON Syntax:

{
  "functions": ["string", ...]
}

--sync-config (structure)

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 -> (structure)

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.

Shorthand Syntax:

conflictHandler=string,conflictDetection=string,lambdaConflictHandlerConfig={lambdaConflictHandlerArn=string}

JSON Syntax:

{
  "conflictHandler": "OPTIMISTIC_CONCURRENCY"|"LAMBDA"|"AUTOMERGE"|"NONE",
  "conflictDetection": "VERSION"|"NONE",
  "lambdaConflictHandlerConfig": {
    "lambdaConflictHandlerArn": "string"
  }
}

--caching-config (structure)

The caching configuration for the resolver.

ttl -> (long)

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)

Shorthand Syntax:

ttl=long,cachingKeys=string,string

JSON Syntax:

{
  "ttl": long,
  "cachingKeys": ["string", ...]
}

--max-batch-size (integer)

The maximum batching size for a resolver.

--runtime (structure)

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 .

Shorthand Syntax:

name=string,runtimeVersion=string

JSON Syntax:

{
  "name": "APPSYNC_JS",
  "runtimeVersion": "string"
}

--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 .

--metrics-config (string)

Enables or disables enhanced resolver metrics for specified resolvers. Note that metricsConfig won’t be used unless the resolverLevelMetricsBehavior value is set to PER_RESOLVER_METRICS . If the resolverLevelMetricsBehavior is set to FULL_REQUEST_RESOLVER_METRICS instead, metricsConfig will be ignored. However, you can still set its value.

metricsConfig can be ENABLED or DISABLED .

Possible values:

• ENABLED
• DISABLED

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

• json
• text
• table
• yaml
• yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on
• off
• auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

• base64
• raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.
