get-resolver

Description

Retrieves a Resolver object.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-resolver
--api-id <value>
--type-name <value>
--field-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--api-id (string)

The API ID.

--type-name (string)

The resolver type name.

--field-name (string)

The resolver field name.

--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.

(string)

syncConfig -> (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 .
