1. Which tools folks have been using to manage their feature flags 2. What do they like and dislike the most in the solution they currently use
Also, which factors led you to choose your current tool?
There is an internal initiative recently asking for dynamic config based feature control. The dynamic config is an RPC-based data push to the running services, which are expected to handle the config changes without restarting. It sounds less disruptive but may require careful cleanup for some features, in which case the cmd flag with a restart is much easier to implement.
