What? It's the absolute truth. If someone's wall post or tweet goes missing, it's totally inconsequential. "Social graph" - LOL.

- taligent 14y agoSure. But if a person or a photo data object goes missing ? Facebook has different data stores for each of their features so I imagine the loss of a person would be pretty nasty as would a photo data object that multiple people have tagged or commented on. My point is that when you are the size of Facebook, Twitter etc a loss of data in 0.001% of cases equates to a LOT of data and relationships.
- lttlrck 14y agoYou think FB doesn't consider durability and consistency essential? With almost one billion users?! Wow. Whether it is consequential or not is completely beside the point. As is whether you understand the "social graph".
- nerd_in_rage 14y agoEventual consistency, yes. What I'm saying is if a few pics disappear for a half hour while things resolve themselves, nobody is going to care... or likely notice. It's not a bank. By the way, I believe social networking is mostly bullshit, which is my "LOL" at the "social graph".
- einhverfr 14y agoEventual consistency however provides no guarantee of consistency unless it is backed by absolute local consistency on every node. Don't you run into CAP theorem problems otherwise?
