Your data fits in RAM
So, let's say my system is currently backed by MySQL or PostgreSQL, and that is not fungible. How would one move that data into RAM, including writes? And, how would one maintain some level of safety in the event of a crash? i.e. I don't really care if I lose X amount of time worth of data (say, five minutes), but I do care that when I reboot the system, the database comes back from disk into RAM in a consistent state.<p>Is there some off-the-shelf solution to this problem? And, if so, why isn't it talked about more? Every CMS ever, for example, would be very well-served by something like this. My entire website's database, all ~100k comments and pages and issues and all 60k users, is only 1.4GB, and performance is always a problem. I don't care if I lose a couple minutes worth of comments in the event of a system reboot or crash. So, why can't I just turn that feature (in-memory with eventual on-disk consistency, or whatever you'd want to call it) on and forget about it?
