  • executionArn — (String)

    The Amazon Resource Name (ARN) of the execution.

var params = {
  mapRunArn: 'STRING_VALUE', /* required */
  maxConcurrency: 'NUMBER_VALUE',
  toleratedFailureCount: 'NUMBER_VALUE',
  toleratedFailurePercentage: 'NUMBER_VALUE'
};
stepfunctions.updateMapRun(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • mapRunArn — (String)

    The Amazon Resource Name (ARN) of a Map Run.

  • maxConcurrency — (Integer)

    The maximum number of child workflow executions that can be specified to run in parallel for the Map Run at the same time.

  • toleratedFailurePercentage — (Float)

    The maximum percentage of failed items before the Map Run fails.

  • toleratedFailureCount — (Integer)

    The maximum number of failed items before the Map Run fails.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

Callback (callback):

• function(err, data) { ... }
