Well, it looks like the sibling threads are very interested to know where the need comes from to even _have_ 1.2 million queries per second. How does that break down? How much is that just core functionality versus analytics and tracking?
That's core functionality, not analytics. Nearly all of that is browsing, ordering, location updates, etc. The dismissive comments are amusing and show a lack of understanding of how the business works and, subsequently, the technology required to power the end-to-end flow for users.
Of course we don't know your business; we do back-of-envelope math based on our own experiences and of course a lot of assumptions about yours. Those numbers are just... impressive... or unbelievable... depending on where you're coming from.
