What are feature flags and how do they affect deployment?

Feature flags are tools that allow developers to enable or disable features in a software application without deploying new code. They can significantly impact deployment by allowing teams to release features incrementally, test in production, and roll back features quickly if issues arise.

Can you explain the benefits of using feature flags?

Sure! The benefits include safer deployments, the ability to test features with real users, reduced risk of bugs, and the flexibility to roll out features gradually.

Are there any downsides to using feature flags?

Yes, potential downsides include increased complexity in code management, the risk of technical debt if flags are not removed, and the need for thorough testing to ensure flags don't introduce bugs.

How do teams manage feature flags effectively?

Teams can manage feature flags by establishing clear guidelines for their use, regularly reviewing and cleaning up old flags, and using tools that provide visibility into the status of each flag.
