The tutorial discusses the implementation of kill switches in a Java Spring Boot application using the LaunchDarkly SDK. A kill switch allows developers to quickly disable features in their application without causing additional disruption. The process involves creating a feature flag, integrating the LaunchDarkly client, and configuring the flag to control the behavior of specific code paths. The tutorial also covers how to integrate a third-party API and demonstrate the capabilities of the kill switches. By following these steps, developers can add kill switches to their Java Spring Boot application and improve the reliability and maintainability of their software.
