Topic: But server processed wrong submission! Understanding Race Condition

You built an application. Then you scaled up your application, added more user, added more servers. Everything would seem fine until at some moment, server may get different outcomes processing data with the same data in high traffic application. It might be race condition: altering/submitting data in unsafe manner. It can be SQL, thread, or even multi-machine communication. Race condition is catastrophic because it does not show up in small, low-traffic application. In this talk, i will tell what race condition is and we will see common pitfall in building high traffic application. Of course we will also discuss on how to avoid it in Rails.
