AWS::Evidently::Launch SegmentOverride

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.

This sructure is an array of up to six segment override objects. Each of these objects specifies a segment that you have already created, and defines the traffic split for that segment.


To declare this entity in your Amazon CloudFormation template, use the following syntax:


{ "EvaluationOrder" : Integer, "Segment" : String, "Weights" : [ GroupToWeight, ... ] }


EvaluationOrder: Integer Segment: String Weights: - GroupToWeight



A number indicating the order to use to evaluate segment overrides, if there are more than one. Segment overrides with lower numbers are evaluated first.

Required: Yes

Type: Integer

Update requires: No interruption


The ARN of the segment to use for this override.

Required: Yes

Type: String

Update requires: No interruption


The traffic allocation percentages among the feature variations to assign to this segment. This is a set of key-value pairs. The keys are variation names. The values represent the amount of traffic to allocate to that variation for this segment. This is expressed in thousandths of a percent, so a weight of 50000 represents 50% of traffic.

Required: Yes

Type: List of GroupToWeight
