AWS::Evidently::Segment - Amazon CloudFormation
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

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.
