Instance Method Details

#batch_evaluate_feature(params = {}) ⇒ Types::BatchEvaluateFeatureResponse

This operation assigns feature variation to user sessions. For each user session, you pass in an entityID that represents the user. Evidently then checks the evaluation rules and assigns the variation.

The first rules that are evaluated are the override rules. If the user's entityID matches an override rule, the user is served the variation specified by that rule.

Next, if there is a launch of the feature, the user might be assigned to a variation in the launch. The chance of this depends on the percentage of users that are allocated to that launch. If the user is enrolled in the launch, the variation they are served depends on the allocation of the various feature variations used for the launch.

If the user is not assigned to a launch, and there is an ongoing experiment for this feature, the user might be assigned to a variation in the experiment. The chance of this depends on the percentage of users that are allocated to that experiment. If the user is enrolled in the experiment, the variation they are served depends on the allocation of the various feature variations used for the experiment.

If the user is not assigned to a launch or experiment, they are served the default variation.

#create_experiment(params = {}) ⇒ Types::CreateExperimentResponse

Creates an Evidently experiment. Before you create an experiment, you must create the feature to use for the experiment.

An experiment helps you make feature design decisions based on evidence and data. An experiment can test as many as five variations at once. Evidently collects experiment data and analyzes it by statistical methods, and provides clear recommendations about which variations perform better.

Don't use this operation to update an existing experiment. Instead, use UpdateExperiment.

Options Hash (params):

• :description (String) —

  An optional description of the experiment.

• :metric_goals (required, Array<Types::MetricGoalConfig>) —

  An array of structures that defines the metrics used for the experiment, and whether a higher or lower value for each metric is the goal.

• :name (required, String) —

  A name for the new experiment.

• :online_ab_config (Types::OnlineAbConfig) —

  A structure that contains the configuration of which variation to use as the "control" version. tThe "control" version is used for comparison with other variations. This structure also specifies how much experiment traffic is allocated to each variation.

• :project (required, String) —

  The name or ARN of the project that you want to create the new experiment in.

• :randomization_salt (String) —

  When Evidently assigns a particular user session to an experiment, it must use a randomization ID to determine which variation the user session is served.

• :sampling_rate (Integer) —

  The portion of the available audience that you want to allocate to this experiment, in thousandths of a percent. The available audience is the total audience minus the audience that you have allocated to overrides or current launches of this feature.

  This is represented in thousandths of a percent. For example, specify 10,000 to allocate 10% of the available audience.

• :tags (Hash<String,String>) —

  Assigns one or more tags (key-value pairs) to the experiment.

  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 Amazon Web Services and are interpreted strictly as strings of characters.

   <p>You can associate as many as 50 tags with an experiment.</p> <p>For more information, see <a href="https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html">Tagging Amazon Web Services resources</a>.</p>

• :description (String) —

  An optional description of the feature.

• :entity_overrides (Hash<String,String>) —

  Specify users that should always be served a specific variation of a feature. Each user is specified by a key-value pair . For each key, specify a user by entering their user ID, account ID, or some other identifier. For the value, specify the name of the variation that they are to be served.

• :evaluation_strategy (String) —

  Specify ALL_RULES to activate the traffic allocation specified by any ongoing launches or experiments. Specify DEFAULT_VARIATION to serve the default variation to all users instead.

• :name (required, String) —

  The name for the new feature.

• :project (required, String) —

  The name or ARN of the project that is to contain the new feature.

• :tags (Hash<String,String>) —

  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 Amazon Web Services and are interpreted strictly as strings of characters.

   <p>You can associate as many as 50 tags with a feature.</p> <p>For more information, see <a href="https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html">Tagging Amazon Web Services resources</a>.</p>

def create_feature(params = {}, options = {})
  req = build_request(:create_feature, params)
  req.send_request(options)
end

#create_launch(params = {}) ⇒ Types::CreateLaunchResponse

Creates a launch of a given feature. Before you create a launch, you must create the feature to use for the launch.

You can use a launch to safely validate new features by serving them to a specified percentage of your users while you roll out the feature. You can monitor the performance of the new feature to help you decide when to ramp up traffic to more users. This helps you reduce risk and identify unintended consequences before you fully launch the feature.

Don't use this operation to update an existing launch. Instead, use UpdateLaunch.

Examples:

Request syntax with placeholder values

resp = client.create_launch({
  description: "Description",

#evaluate_feature(params = {}) ⇒ Types::EvaluateFeatureResponse

This operation assigns a feature variation to one given user session. You pass in an entityID that represents the user. Evidently then checks the evaluation rules and assigns the variation.

The first rules that are evaluated are the override rules. If the user's entityID matches an override rule, the user is served the variation specified by that rule.

Next, if there is a launch of the feature, the user might be assigned to a variation in the launch. The chance of this depends on the percentage of users that are allocated to that launch. If the user is enrolled in the launch, the variation they are served depends on the allocation of the various feature variations used for the launch.

If the user is not assigned to a launch, and there is an ongoing experiment for this feature, the user might be assigned to a variation in the experiment. The chance of this depends on the percentage of users that are allocated to that experiment. If the user is enrolled in the experiment, the variation they are served depends on the allocation of the various feature variations used for the experiment.

If the user is not assigned to a launch or experiment, they are served the default variation.

Examples:

Request syntax with placeholder values

resp = client.evaluate_feature({
  entity_id: "EntityId", # required
  evaluation_context: "JsonValue",
  feature: "FeatureName", # required
  project: "ProjectRef", # required
})

Response structure

resp.details #=> String
resp.reason #=> String
resp.value.bool_value #=> Boolean
resp.value.double_value #=> Float
resp.value.long_value #=> Integer
resp.value.string_value #=> String
resp.variation #=> String

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :entity_id (required, String) —

  An internal ID that represents a unique user of the application. This entityID is checked against any override rules assigned for this feature.

• :evaluation_context (String) —

  A JSON block of attributes that you can optionally pass in. This JSON block is included in the evaluation events sent to Evidently from the user session.

  SDK automatically handles json encoding and base64 encoding for you when the required value (Hash, Array, etc.) is provided according to the description.

• :feature (required, String) —

  The name of the feature being evaluated.

• :project (required, String) —

resp.timestamps #=> Array
resp.timestamps[0] #=> Time

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :base_stat (String) —

  The statistic used to calculate experiment results. Currently the only valid value is mean, which uses the mean of the collected values as the statistic.

• :end_time (Time, DateTime, Date, Integer, String) —

  The date and time that the experiment ended, if it is completed. This must be no longer than 30 days after the experiment start time.

• :experiment (required, String) —

  The name of the experiment to retrieve the results of.

• :metric_names (required, Array<String>) —

  The names of the experiment metrics that you want to see the results of.

• :period (Integer) —

  In seconds, the amount of time to aggregate results together.

• :project (required, String) —

  The name or ARN of the project that contains the experiment that you want to see the results of.

• :report_names (Array<String>) —

  The names of the report types that you want to see. Currently, BayesianInference is the only valid value.

• :result_stats (Array<String>) —

  The statistics that you want to see in the returned results.

  • PValue specifies to use p-values for the results. A p-value is used in hypothesis testing to measure how often you are willing to make a mistake in rejecting the null hypothesis. A general practice is to reject the null hypothesis and declare that the results are statistically significant when the p-value is less than 0.05.

  • ConfidenceInterval specifies a confidence interval for the results. The confidence interval represents the range of values for the chosen metric that is likely to contain the true difference between the baseStat of a variation and the baseline. Evidently returns the 95% confidence interval.

  • TreatmentEffect is the difference in the statistic specified by the baseStat parameter between each variation and the default variation.

  • BaseStat returns the statistical values collected for the metric for each variation. The statistic uses the same statistic specified in the baseStat parameter. Therefore, if baseStat is mean, this returns the mean of the values collected for each variation.

• :start_time (Time, DateTime, Date, Integer, String) —

  The date and time that the experiment started.

• :treatment_names (required, Array<String>) —

  The names of the experiment treatments that you want to see the results for.

Returns:

• (Types::GetExperimentResultsResponse) —

  Returns a response object which responds to the following methods:

  • #details => String
  • #reports => Array<Types::ExperimentReport>
  • #results_data => Array<Types::ExperimentResultsData>

#tag_resource(params = {}) ⇒ Struct

Assigns one or more tags (key-value pairs) to the specified CloudWatch Evidently resource. Projects, features, launches, and experiments can be tagged.

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 Amazon Web Services and are interpreted strictly as strings of characters.

You can use the TagResource action with a resource that already has tags. If you specify a new tag key for the resource, this tag is appended to the list of tags associated with the alarm. If you specify a tag key that is already associated with the resource, the new tag value that you specify replaces the previous value for that tag.

You can associate as many as 50 tags with a resource.

For more information, see Tagging Amazon Web Services resources.

Examples:

Request syntax with placeholder values

resp = client.tag_resource({
  resource_arn: "Arn", # required
  tags: { # required
    "TagKey" => "TagValue",
  },
})

Parameters:

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :add_or_update_variations (Array<Types::VariationConfig>) —

  To update variation configurations for this feature, or add new ones, specify this structure. In this array, include any variations that you want to add or update. If the array includes a variation name that already exists for this feature, it is updated. If it includes a new variation name, it is added as a new variation.

• :default_variation (String) —

  The name of the variation to use as the default variation. The default variation is served to users who are not allocated to any ongoing launches or experiments of this feature.

• :description (String) —

  An optional description of the feature.

• :entity_overrides (Hash<String,String>) —

  Specified users that should always be served a specific variation of a feature. Each user is specified by a key-value pair . For each key, specify a user by entering their user ID, account ID, or some other identifier. For the value, specify the name of the variation that they are to be served.

• :evaluation_strategy (String) —

  Specify ALL_RULES to activate the traffic allocation specified by any ongoing launches or experiments. Specify DEFAULT_VARIATION to serve the default variation to all users instead.

• :feature (required, String) —

  The name of the feature to be updated.

• :project (required, String) —

  The name or ARN of the project that contains the feature to be updated.

• :remove_variations (Array<String>) —

  Removes a variation from the feature. If the variation you specify doesn't exist, then this makes no change and does not report an error.

  This operation fails if you try to remove a variation that is part of an ongoing launch or experiment.

Returns:

• (Types::UpdateFeatureResponse) —

  Returns a response object which responds to the following methods:

  • #feature => Types::Feature

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :description (String) —

  An optional description for the launch.

• :groups (Array<Types::LaunchGroupConfig>) —

  An array of structures that contains the feature and variations that are to be used for the launch.

• :launch (required, String) —

  The name of the launch that is to be updated.

• :metric_monitors (Array<Types::MetricMonitorConfig>) —

  An array of structures that define the metrics that will be used to monitor the launch performance.

• :project (required, String) —

  The name or ARN of the project that contains the launch that you want to update.

• :randomization_salt (String) —

  When Evidently assigns a particular user session to a launch, it must use a randomization ID to determine which variation the user session is served. This randomization ID is a combination of the entity ID and randomizationSalt. If you omit randomizationSalt, Evidently uses the launch name as the randomizationSalt.

• :scheduled_splits_config (Types::ScheduledSplitsLaunchConfig) —

  An array of structures that define the traffic allocation percentages among the feature variations during each step of the launch.

Returns:

• (Types::UpdateLaunchResponse) —
