alt Hacker NewsIf you’re live streaming video, you can make sure every frame is a P-frame which brings your bandwidth costs to a minimum, but then a lost packet completely permanently disables the stream. Or you periodically refresh the stream with I-frames sent over a reliable channel so that lost packets corrupt the video going forward only momentarily.
Sure, if performance characteristics were the same, people would go for strong consistency. The reason many different consistency models are defined is that there’s different tradeoffs that are preferable to a given problem domain with specific business requirements.
If the video is streaming, people don't really care if a few frames drop, hell, most won't notice.
It's only when several frames in a row are dropped that people start to notice, and even then they rarely care as long as the message within the video has enough data points for them to make an (educated) guess.
