What are the situations where you did not (or would not) opt to use feature flags?

  I usually skip feature flags for things like bug fixes where the risk that my 'fix' is actually worse than the initial bug is very small, or changes where it cannot make sense to have both modes operating at once. An example of this might be a new billing scheme, where the old system billed by the item, and the new system billed by the pound. There might not be a technical reason why both cannot co-exist, but it would cause marketing/support headaches to have some customers billed one way, and some billed another. One surprising use case that I have had great success with, though, is in database migrations. I detailed my approach here, if you are interested: http://blog.launchdarkly.com/feature-flagging-to-mitigate-risk-in-database-migration/ http://blog.launchdarkly.com/feature-flagging-to-mitigate-ri...

      No problem! If you happen to be in the SF Bay area (and if you will forgive the self-promotion) I'm going to be presenting this at a meetup in a couple weeks: http://www.meetup.com/AWS-EASTBAY/events/232870012/ http://www.meetup.com/AWS-EASTBAY/events/232870012/
