Abstract: The disclosed embodiments provide a system for performing unified management of targeting attributes in A/B tests. During operation, the system obtains attribute configurations for attributes to be used in subsequent targeting of users by A/B tests. Next, the system configures, based on the attribute configurations, onboarding of the attributes from an offline environment, a near-real-time environment, and an online environment. During an A/B test, the system retrieves values of one or more of the attributes for a user from locations specified in the attribute configurations. Finally, the system outputs the values with targeting conditions for the A/B test for use in selecting a treatment assignment for the user in the A/B test.

Abstract: The disclosed embodiments provide a system that uses A/B testing to safely terminate unused experiments. During operation, the system determines a first A/B test that matches one or more criteria for removal from an A/B testing platform. Next, the system initiates a first ramp-down of the first A/B test to observe an effect of a control variant on a performance metric for the first A/B test. When the effect includes a change in the performance metric, the system automatically removes code blocks that use the first A/B test on the A/B testing platform and terminates the first A/B test.

Abstract: The disclosed embodiments provide a system for evaluating targeting conditions for A/B tests. During operation, the system obtains a test configuration containing targeting conditions for an A/B test, wherein the targeting conditions include attributes of one or more segments of users and operators to be applied to the attributes. Next, the system identifies an operator between a first targeting condition that can be evaluated locally and a second targeting condition that requires a remote call to evaluate. The system then evaluates the first targeting condition without evaluating the second targeting condition to produce an output value of the first targeting condition. When application of the operator to the output value produces a Boolean value, the system returns the Boolean value as an evaluation result for a portion of the test configuration represented by the operator, the first targeting condition, and the second targeting condition.
