100% of people writing a database know about filesystem options like DIRECT and SYNC, and that is the subject of this paper.

Also, most of the network-attached storage we people use is in the form of things like EBS, which is very careful to imitate the behavior of a real disk, but with different performance and some different (albeit very rare) failure modes.

100% of people writing databases also know how fsync() and msync() work. I interpreted this thread as being targeted at a wider audience.

It's literally for people writing their own database. Why would you interpret it differently?
