For businesses? Sure there's gonna be a lot of limits. Only 7 billion humans so that sorta limits any user tables. Only so many things those people can buy each day, so that limits your orders table.

VISA does what, 150M transactions per day? I was doing more volume than that for telephone calls a couple years ago with a $5K server and a default install of MSSQL. (Full ACID, updating balances -- yes I know a CC tx is probably heavier than a VoIP call but still.) At 4KB per tx, VISA could use VoltDB and store all tx's in RAM for a week for like a million or two.

An 150M a day today is not that much more than it was 15 years ago it seems. (50-100% more?).

For many, many, businesses, data size just isn't an issue any more cost wise, and soon won't be a technical challenge at all either. Yet 10, 20 years ago, we're talking 8-digit+ implementations.

Sure there's some things that grow faster, like all this increased tracking. But in general?
