Object Prevalence: Get Rid of Your Database?

[Ken Carpenter]

Here's a somewhat interesting article on Slashdot. It talks about using object-oriented persistence rather than a RDBMS. They talk about 9000 times better performance for certain "queries".

Thanks, I saw this article this morning, too.

I bet you can get an equivalent performance or even higher performance with the Freeze evictor, provided that you have a sufficiently large evictor queue.

Of course, the evictor doesn't log each update. But you can set "save upon mutating operation" strategy, which might even be faster than writing to a log if the per-object state isn't too large.
