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.
The pattern that you define for a segment is matched against the value of evaluationContext, which
          is passed into Evidently in the EvaluateFeature operation,
          when Evidently assigns a feature variation to a user.
Syntax
To declare this entity in your Amazon CloudFormation template, use the following syntax:
JSON
{ "Type" : "AWS::Evidently::Segment", "Properties" : { "Description" :String, "Name" :String, "Pattern" :String, "Tags" :[ Tag, ... ]} }
YAML
Type: AWS::Evidently::Segment Properties: Description:StringName:StringPattern:StringTags:- Tag
Properties
- Description
- 
                    An optional description for this segment. Required: No Type: String Minimum: 0Maximum: 160Update requires: No interruption 
- Name
- 
                    A name for the segment. Required: Yes Type: String Pattern: [-a-zA-Z0-9._]*Minimum: 1Maximum: 127Update requires: No interruption 
- Pattern
- 
                    The pattern to use for the segment. For more information about pattern syntax, see Segment rule pattern syntax. Required: No Type: String Minimum: 1Maximum: 1024Update requires: No interruption 
- 
                    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 Amazon and are interpreted strictly as strings of characters. You can associate as many as 50 tags with a feature. For more information, see Tagging Amazon resources. Required: No Type: Array of Tag Update requires: No interruption 
Return values
Ref
When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the ARN of the segment. 
            For example, arn:aws:evidently:us-west-2:123456789012:segment/australiaSegment
Fn::GetAtt
The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.
For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.
- Arn
- 
                            The ARN of the segment. For example, arn:aws:evidently:us-west-2:123456789012:segment/australiaSegment
