> Am I reading the second figure right? Facebook can do 130*10^6 queries/second == 130,000,000 queries/second?! That sounds totally plausible to me. Also keep in mind they didn't say what system this is. It's often true that 1 request to a frontend system becomes 1 each to 10 different backend services owned by different teams and then 20+ total to some database/storage layer many of them depend on. The qps at the bottom of the stack is in general a lot higher than the qps at the top, though with caching and static file requests and such this isn't a universal truth. |
