the big (BIG) difference is in commit performance. normal DBs don't trust RAM a bit, all commits have to hit the platter. Of course, many storage subsystems specify battery-backed writeback caches. but, the disruption is not about what's possible, but how common it becomes. small servers (and VMs) typically put the DB in single 7200rpm disks (or even worse, on RAID5) and it works OK for huge segments; but soon it would be 'normal' to use SSDs and go from less than 100 commits/sec to a few thousands, with no effort at all. i do think it will have an effect on how web apps are written, and it might shift some optimization efforts to the platform; but to go from there to Java is a big (backwards) leap. -- Javier -- You received this message because you are subscribed to the Google Groups "Django users" group.
