This list discourages top posting. You’re asked to place your reply at the bottom
You haven’t laid out you’re application architecture (how many clients, who is reading who is writing, etc). Caching doesn’t mean your database is any less crash proof. At that rate of activity, depending on architecture, you could lose updates in all sorts of crash scenarios.
As for crash proof, I meant that once my client app is told that her update request was committed, it mustn't get lost (hdd failure apart of course). And I can't wait to flush the cache before telling to the app :"committed".
I can replicate also the cache on the standby PC of course.
