AWS::Evidently::SegmentCfnSegment
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.html#CloudWatch-Evidently-segments-syntax) . 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.
Import
import { CfnSegment } from 'aws-cdk-lib/aws-evidently';Or use the module namespace:
import * as evidently from 'aws-cdk-lib/aws-evidently';
// evidently.CfnSegmentProperties
Configuration passed to the constructor as CfnSegmentProps.
nameRequiredstringA name for the segment.
descriptionOptionalstringAn optional description for this segment.
patternOptionalstringThe pattern to use for the segment. For more information about pattern syntax, see [Segment rule pattern syntax](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Evidently-segments.html#CloudWatch-Evidently-segments-syntax) .
tagsOptionalCfnTag[]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) .
