Techniques are provided for feature toggle management with application behavior point-in-time restoration using event sourcing. One method comprises maintaining feature toggle events for features of an application, wherein each feature toggle event comprises an indication of an event time of the respective feature toggle event for a given feature; receiving a request to execute the application with feature toggle settings associated with an indicated point-in-time; and initiating an execution of the application with the feature toggle settings associated with the indicated point-in-time by processing the feature toggle events having an event time up to the indicated point-in-time. Event sourcing techniques may be employed to store the plurality of feature toggle events for the plurality of features in an event repository. The application may consume the feature toggle events having an event time up to the indicated point-in-time and may ignore the feature toggle events having an event time after the indicated point-in-time.

Feature toggle management with application behavior point-in-time restoration using event sourcing

A system and method for reducing execution errors make by a software service are disclosed. The service has several features whose execution paths are switched on or off by corresponding feature toggles, i.e. flags in a configuration database. The performance, and especially error generation, of each feature is monitored automatically and an instantaneous error rate is produced. When the error rate exceeds a given threshold error rate for a particular feature, the corresponding toggle is disabled in the configuration database and the service is triggered to restart using the updated toggles, thereby disabling the problematic feature. The system and method also determine whether the error rate increased due to a transient error condition, such as a data link drop or a secondary service restart, and re-enable the toggle when the error condition has passed.
