New Guilty until proven innocent?

New No, you said something stupid
"Just use transactions" is not sufficient to solve concurrency problems under load.

I described a real-world case where it was not to demonstrate the point.

You were "Presumed innocent until proven guilty", but the proof was pretty easy to produce.

As for my parting comment about whether you had relevant experience, that is an educated guess at best, which you could easily confirm or deny. However I should point out that most programmers don't have the kind of experience that I described, so it is no insult to suggest that you don't either. (Neither did I until I moved to LA.)

Cheers,
Ben

New You don't seem to disagree anywhere
"Just use transactions" is not sufficient to solve concurrency problems under load.

You didn't recommend going away from transactions anywhere that I saw, just tuning them. Thus, you seem to agree with me.


As for my parting comment about whether you had relevant experience, that is an educated guess at best, which you could easily confirm or deny.

I have worked on heavy-transaction systems. But, I will admit that most of my projects tend to be management information and decision support systems rather than high-volume transactions.

New I disagree with, "Fixed!"
While databases and transactions help with a broad range of concurrency issues (but not all - there are cases where you wouldn't want to use them), they are not a pancea that solves all of your problems. It would be nice if the world was that simple, but it isn't.

Incidentally what would you call "heavy load"? For instance what rate of transactions would that be? 10s per hour? 100s per hour? 1000s per hour, please give us a ballpark.

Thanks,
Ben

I KNOW I shouldn’t think about it, I’ll scare myself to death but after seventeen hours in the air, I can’t get the worst case scenario out of my head.

No, not a plane crash. I’m convinced that I am breathing more farts than air.
