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
My point is more that 90% of use cases don’t need that, and for those that do, you can’t just slap eg. Cassandra at it and pretend it’s a relational database.
