Delivery

Managing Feature Flags as Temporary Code

A feature flag can make a risky change easier to release. Instead of making deployment and exposure happen at the same moment, the team can deploy code while keeping new behavior disabled, enable it for a limited audience, observe the result, and turn it off without rebuilding the application. That flexibility has a cost. Every flag introduces another condition that can affect behavior. If old flags remain indefinitely, developers must reason about combinations that no longer serve a useful purpose.
