LIVE SESSION — LLD MEDIUM
Interviewer
Let's start with clarifications. What's the expected scale — how many users are we designing for?
You
I'd assume around 10 million active users, with peak traffic during meal times.
Interviewer
Good. And are we optimising for consistency or availability in case of a partition?
You
Availability. Users should always be able to place orders even if some data is slightly stale.
Interviewer
That's a reasonable trade-off. Walk me through your high-level component design.
