Interesting reading that.
Caffeine is about the search index. But GFS2 is designed specifically for applications like Gmail and YouTube, applications that - unlike an indexing system - are served up directly to the end user. Such apps require ultra-low latency, and that's not something the original GFS was designed for.
Wave being one of those ultra-low latency applications too presumably.
