>From my experience most databases are just tpo small. Their operations finish before there can be a deadlock. Same for race conditions - most developer don't know about them, because they never stumbled upon them. I am matching regularly discussions if a database is already to big when holding 10.000 records in the whole cluster...
Ha. Yes. So true.
I see Stack Overflow posts where somebody explains that their query takes ages on their Huge!!1! database. Then it turns out the query takes 0.2 seconds on a 400MB table.
