AWS::Evidently Construct Library

This module is part of the AWS Cloud Development Kit project.

import evidently "github.com/aws/aws-cdk-go/awscdk"

There are no official hand-written (L2) constructs for this service yet. Here are some suggestions on how to proceed:

There are no hand-written (L2) constructs for this service yet. However, you can still use the automatically generated L1 constructs, and use this service exactly as you would using CloudFormation directly.

For more information on the resources and properties available for this service, see the CloudFormation documentation for AWS::Evidently.

(Read the CDK Contributing Guide and submit an RFC if you are interested in contributing to this construct library.)

Functions

func CfnExperiment_CFN_RESOURCE_TYPE_NAME 

func CfnExperiment_CFN_RESOURCE_TYPE_NAME() *string

func CfnExperiment_IsCfnElement 

func CfnExperiment_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of `instanceof` to allow stack elements from different versions of this library to be included in the same stack.

Returns: The construct as a stack element or undefined if it is not a stack element.

func CfnExperiment_IsCfnResource 

func CfnExperiment_IsCfnResource(construct constructs.IConstruct) *bool

Check whether the given construct is a CfnResource.

func CfnExperiment_IsConstruct 

func CfnExperiment_IsConstruct(x interface{}) *bool

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.

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

func CfnFeature_CFN_RESOURCE_TYPE_NAME 

func CfnFeature_CFN_RESOURCE_TYPE_NAME() *string

func CfnFeature_IsCfnElement 

func CfnFeature_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Returns: The construct as a stack element or undefined if it is not a stack element.

A CloudFormation `AWS::Evidently::Experiment`.

Creates or updates an Evidently *experiment* . Before you create an experiment, you must create the feature to use for the experiment.

An experiment helps you make feature design decisions based on evidence and data. An experiment can test as many as five variations at once. Evidently collects experiment data and analyzes it by statistical methods, and provides clear recommendations about which variations perform better.

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

A CloudFormation `AWS::Evidently::Launch`.

Creates or updates a *launch* of a given feature. Before you create a launch, you must create the feature to use for the launch.

You can use a launch to safely validate new features by serving them to a specified percentage of your users while you roll out the feature. You can monitor the performance of the new feature to help you decide when to ramp up traffic to more users. This helps you reduce risk and identify unintended consequences before you fully launch the feature.

Use this structure to specify different traffic splits for one or more audience *segments* .

A segment is a portion of your audience that share one or more characteristics. Examples could be Chrome browser users, users in Europe, or Firefox browser users in Europe who also fit other criteria that your application collects, such as age.

For more information, see [Use segments to focus your audience](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Evidently-segments.html) .

A CloudFormation `AWS::Evidently::Segment`.

Creates or updates a *segment* of your audience. A segment is a portion of your audience that share one or more characteristics. Examples could be Chrome browser users, users in Europe, or Firefox browser users in Europe who also fit other criteria that your application collects, such as age.

Using a segment in an experiment limits that experiment to evaluate only the users who match the segment criteria. Using one or more segments in a launch allow you to define different traffic splits for the different audience segments.

For more information about segment pattern syntax, see [Segment rule pattern syntax](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Evidently-segments-syntax.html) .

The pattern that you define for a segment is matched against the value of `evaluationContext` , which is passed into Evidently in the [EvaluateFeature](https://docs.aws.amazon.com/cloudwatchevidently/latest/APIReference/API_EvaluateFeature.html) operation, when Evidently assigns a feature variation to a user.

	// Assigns one or more tags (key-value pairs) to the feature.

	// Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.
	//
	// Tags don't have any semantic meaning to AWS and are interpreted strictly as strings of characters.
	//
	// You can associate as many as 50 tags with a feature.
	//
	// For more information, see [Tagging AWS resources](https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html) .
