If you need to run queries that aggregate big amounts of data in a reasonable time and cost, you’ll need something built for it. For example, with a column oriented file format instead of the row oriented file format found in traditional relational databases
And the key word “big” here is far bigger than most engineers need to deal with. Hell, most supposed “big data” problems I’ve seen people try to tackle are small enough to fit the whole database into memory.
