[Freecats-Dev] Introduction to Object Prevalence

[Henri Chorand]

Hi all,

Whatever the development roadmap that awaits us, I found this very
interesting article in Slashdot:
http://developers.slashdot.org/developers/03/03/03/1220222.shtml?tid=156

The idea is to forget, once and for all, about databases, by keeping all
data in RAM (it should work for any reasonably sized TM, where the worst I
saw yet was around 20 Mb) and to use a simple mechanism where:
- You write these data on disk from time to time (when the server is not
busy)
- You log all changes in a separate log file (so that you can recover nicely
from a crash/power failure)

And if RAM becomes scarce, at least the OS' caching module does it
seamlessly for you.
And... it's available in a variety of languages (or going to be so soon) -
it's not really language-specific.


It refers to:

For Python (a very new project):

I wonder if one of the mailing list subscribers has some experience of O.P.
