What is a Feature Flag in Software and Why Is It Useful? 

Glad it was helpful!

Hey Pankaj, Yep it happens at runtime for each invocation. You can also add a caching strategy to not hit the data store for the config too often.

Thanks, that makes sense. One more question, does AppConfig give out of the box caching capabilities somehow or do I need to use some other caching service? If yes which one. Thanks a lot for your time.

Definitely a service to try!

Thank you and welcome! :)

Welcome and thank you for the kind words!

This could work for simple use cases. If you have complex objects this may become more problematic especially if you require version history.

@@BeABetterDev Totally true. We are not doing version history. But so far secrets manager covers our reqs. Anyway thanks for sharing info about that service. Btw i am preparing a presentation about sqs vs eventbridge, vs sns vs s3 vs API gateway events in lambda. How to manage retries, errors, etc. Some of your videos had been helpful for that
