- Clarify the intention
- Does query include all functions like read, write, and search?
- Start making a few assumptions and share your roadmap
- 50% email client market share (others are Apple Mail, MSFT Mail, and Superhuman)
- 50% users who read, write, and send emails every day (~10 queries / day)
- Do a top down analysis
- There are 7B people in the world. 50% have Gmail has their primary account ⇒ 3.5B users
- Assume 50% use Gmail for 10 queries every day. That's 3.5B0.5102460*60 = 1,512T queries per second
