What takes down your biggest sale of the year isn't total load, it's the hot key: one hot partition that throttles while the rest of the table sits idle. Space-based architecture fixes that by taking the database out of the critical path. On AWS serverless you inherit the principle, not the literal implementation, and most projects don't even need it.
