Oh, I assumed we were talking distributed. Fsync to more than one disk. My biases :).

- a1369209993 8y agoFsync to more than one disk is great way to reduce the probability of forced rollback, but simutaneous failure is a still possible. Then again, ACI does assume you aren't having CPU/memory/etc failures, so to the extent that you count anything as guaranteed, it is probably possible to 'guarantee' durablity. My original point was more that "minimally adequate" isn't that hard compared to going from there to a high performance, general purpose system (and also a offhand snipe at SQL).
