Limiting exposure

Use the Limit exposure capability to control which feature treatment customers are exposed to, and increase the number of customers in the feature flag without moving customers in your experiment across treatments. Limit exposure sets the percentage of traffic that is evaluated against the targeting and default rules. For example, if you limit to 75% the traffic to be evaluated, 25% of the traffic is not evaluated by the targeting and default rules and shows the default treatment. To use this feature, do the following:

1. In your selected feature flag, go to the Targeting rules area.
2. Click the Limit exposure button.

3. In the Limit exposure field, enter the percentage of traffic that you want to go through the targeting rules. 

For example, we can start by only including 10% of our traffic in the feature flag, while doing a 20-80 percentage on the included traffic. We can increase exposure by increasing the traffic included in the feature flag, without changing the 20-80 flag. As a result, customers who see the on and off treatments continue to have the same experience while new customers are added to the evaluation.

By default, the Split application exposes 100% of traffic that is evaluated against the targeting and default rules.
