## Example

```ts
new tasks.SageMakerCreateEndpointConfig(this, 'SagemakerEndpointConfig', {
  endpointConfigName: 'MyEndpointConfig',
  productionVariants: [{
  initialInstanceCount: 2,
  instanceType: ec2.InstanceType.of(ec2.InstanceClass.M5, ec2.InstanceSize.XLARGE),
    modelName: 'MyModel',
    variantName: 'awesome-variant',
  }],
});
```

## Initializer

```ts
new SageMakerCreateEndpointConfig(scope: Construct, id: string, props: SageMakerCreateEndpointConfigProps)
```

## Construct Props

- `assign`: { [key: string]: any } — Workflow variables to store in this step.

  **Default:** Not assign variables

  Using workflow variables, you can store data in a step and retrieve that data in future steps.

- `comment`: string — A comment describing this state.

  **Default:** No comment

- `credentials`: [Credentials](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.Credentials.html) — Credentials for an IAM Role that the State Machine assumes for executing the task.

  **Default:** None (Task is executed using the State Machine's execution role)

  This enables cross-account resource invocations.

- `endpointConfigName`: string (required) — The name of the endpoint configuration.

- `heartbeat`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) = None — use `heartbeatTimeout`

- `heartbeatTimeout`: [Timeout](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.Timeout.html) = None — Timeout for the heartbeat.

  [disable-awslint:duration-prop-type] is needed because all props interface in
  aws-stepfunctions-tasks extend this interface

- `inputPath`: string = $ — JSONPath expression to select part of the state to be the input to this state.

  May also be the special value JsonPath.DISCARD, which will cause the effective
  input to be the empty object {}.

- `integrationPattern`: [IntegrationPattern](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.IntegrationPattern.html) — AWS Step Functions integrates with services directly in the Amazon States Language.

  **Default:** `IntegrationPattern.REQUEST_RESPONSE` for most tasks. `IntegrationPattern.RUN_JOB` for the following exceptions: `BatchSubmitJob`, `EmrAddStep`, `EmrCreateCluster`, `EmrTerminationCluster`, and `EmrContainersStartJobRun`.

  You can control these AWS services using service integration patterns.

  Depending on the AWS Service, the Service Integration Pattern availability will vary.

- `kmsKey`: [IKeyRef](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_kms.IKeyRef.html) = None — AWS Key Management Service key that Amazon SageMaker uses to encrypt data on the storage volume attached to the ML compute instance that hosts the endpoint.

- `outputPath`: string = $ — JSONPath expression to select part of the state to be the output to this state.

  May also be the special value JsonPath.DISCARD, which will cause the effective
  output to be the empty object {}.

- `outputs`: any — Used to specify and transform output from the state.

  **Default:** $states.result or $states.errorOutput

  When specified, the value overrides the state output default.
  The output field accepts any JSON value (object, array, string, number, boolean, null).
  Any string value, including those inside objects or arrays,
  will be evaluated as JSONata if surrounded by {% %} characters.
  Output also accepts a JSONata expression directly.

- `productionVariants`: [ProductionVariant](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions_tasks.ProductionVariant.html)[] (required) — An list of ProductionVariant objects, one for each model that you want to host at this endpoint.

  Identifies a model that you want to host and the resources to deploy for hosting it.
  If you are deploying multiple models, tell Amazon SageMaker how to distribute traffic among the models by specifying variant weights.

- `queryLanguage`: [QueryLanguage](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.QueryLanguage.html) = JSONPath — The name of the query language used by the state.

  If the state does not contain a `queryLanguage` field,
  then it will use the query language specified in the top-level `queryLanguage` field.

- `resultPath`: string = $ — JSONPath expression to indicate where to inject the state's output.

  May also be the special value JsonPath.DISCARD, which will cause the state's
  input to become its output.

- `resultSelector`: { [key: string]: any } = None — The JSON that will replace the state's raw result and become the effective result before ResultPath is applied.

  You can use ResultSelector to create a payload with values that are static
  or selected from the state's raw result.

- `stateName`: string — Optional name for this state.

  **Default:** The construct ID will be used as state name

- `tags`: [TaskInput](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.TaskInput.html) — Tags to be applied to the endpoint configuration.

  **Default:** No tags

- `taskTimeout`: [Timeout](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.Timeout.html) = None — Timeout for the task.

  [disable-awslint:duration-prop-type] is needed because all props interface in
  aws-stepfunctions-tasks extend this interface

- `timeout`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) = None — use `taskTimeout`

## Properties

- `endStates`: [INextable](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.INextable.html)[] (required) — Continuable states of this Chainable.

- `id`: string (required) — Descriptive identifier for this chainable.

- `node`: [Node](/cdk/api/v2/docs/constructs.Node.html) (required) — The tree node.

- `PROPERTY_INJECTION_ID`: string (required) (static) — Uniquely identifies this class.

- `startState`: [State](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.State.html) (required) — First state of this Chainable.

- `stateId`: string (required) — Tokenized string that evaluates to the state's ID.

## Methods

- `addCatch(handler: IChainable, props?: CatchProps): TaskStateBase` — Add a recovery handler for this state.

  When a particular error occurs, execution will continue at the error
  handler instead of failing the state machine execution.

- `addPrefix(x: string): void` — Add a prefix to the stateId of this state.

- `addRetry(props?: RetryProps): TaskStateBase` — Add retry configuration for this state.

  This controls if and how the execution will be retried if a particular
  error occurs.

- `bindToGraph(graph: StateGraph): void` — Register this state as part of the given graph.

  Don't call this. It will be called automatically when you work
  with states normally.

- `filterNextables(states: State[]): INextable[]` (static) — Return only the states that allow chaining from an array of states.

- `findReachableEndStates(start: State, options?: FindStateOptions): State[]` (static) — Find the set of end states states reachable through transitions from the given start state.

- `findReachableStates(start: State, options?: FindStateOptions): State[]` (static) — Find the set of states reachable through transitions from the given start state.

  This does not retrieve states from within sub-graphs, such as states within a Parallel state's branch.

- `isConstruct(x: any): boolean` (static) — Checks if `x` is a construct.

  Use this method instead of `instanceof` to properly detect `Construct`
  instances, even when the construct library is symlinked.

  Explanation: in JavaScript, multiple copies of the `constructs` library on
  disk are seen as independent, completely different libraries. As a
  consequence, the class `Construct` in each copy of the `constructs` library
  is seen as a different class, and an instance of one class will not test as
  `instanceof` the other class. `npm install` will not create installations
  like this, but users may manually symlink construct libraries together or
  use a monorepo tool: in those cases, multiple copies of the `constructs`
  library can be accidentally installed, and `instanceof` will behave
  unpredictably. It is safest to avoid using `instanceof`, and using
  this type-testing method instead.

  **Parameters**

  - `x` — Any object.

  **Returns:** true if `x` is an object created from a class which extends `Construct`.

- `jsonata(scope: Construct, id: string, props: SageMakerCreateEndpointConfigJsonataProps): SageMakerCreateEndpointConfig // chainable` (static) — A Step Functions Task using JSONata to create a SageMaker endpoint configuration.

- `jsonPath(scope: Construct, id: string, props: SageMakerCreateEndpointConfigJsonPathProps): SageMakerCreateEndpointConfig // chainable` (static) — A Step Functions Task using JSONPath to create a SageMaker endpoint configuration.

- `metric(metricName: string, props?: MetricOptions): Metric` — Return the given named metric for this Task.

- `metricFailed(props?: MetricOptions): Metric` — Metric for the number of times this activity fails.

- `metricHeartbeatTimedOut(props?: MetricOptions): Metric` — Metric for the number of times the heartbeat times out for this activity.

- `metricRunTime(props?: MetricOptions): Metric` — The interval, in milliseconds, between the time the Task starts and the time it closes.

- `metricScheduled(props?: MetricOptions): Metric` — Metric for the number of times this activity is scheduled.

- `metricScheduleTime(props?: MetricOptions): Metric` — The interval, in milliseconds, for which the activity stays in the schedule state.

- `metricStarted(props?: MetricOptions): Metric` — Metric for the number of times this activity is started.

- `metricSucceeded(props?: MetricOptions): Metric` — Metric for the number of times this activity succeeds.

- `metricTime(props?: MetricOptions): Metric` — The interval, in milliseconds, between the time the activity is scheduled and the time it closes.

- `metricTimedOut(props?: MetricOptions): Metric` — Metric for the number of times this activity times out.

- `next(next: IChainable): Chain` — Continue normal execution with the given state.

- `prefixStates(root: IConstruct, prefix: string): void` (static) — Add a prefix to the stateId of all States found in a construct tree.

- `toStateJson(topLevelQueryLanguage?: QueryLanguage): json` — Return the Amazon States Language object for this state.

- `toString(): string` — Returns a string representation of this construct.

- `with(...mixins: IMixin[]): IConstruct` — Applies one or more mixins to this construct.

  Mixins are applied in order. The list of constructs is captured at the
  start of the call, so constructs added by a mixin will not be visited.
  Use multiple `with()` calls if subsequent mixins should apply to added
  constructs.

  **Parameters**

  - `mixins` — The mixins to apply.

  **Returns:** This construct for chaining
