## Abstract
|
|
|
|
|
|
|
|
|
|
One of the most important lessons learned in distributed computing and concurrency is that
|
|
|
|
|
**shared mutable data is a bad idea**. What is the purpose of a network file system? --
|
|
|
|
|
to **provide a shared mutable data space**.
|
|
|
|
|
There are many other problems with the NFS model at cloud scale.
|
|
|
|
|
NFS remains popular because its killer feature is access to large data sets,
|
|
|
|
|
by network-unaware applications, without having to frst copy them.
|
|
|
|
|
Using existing file systems, *OverlayFS*, and *NVMe-Over-Fabrics*,
|
|
|
|
|
we propose a new approach to achieve blazing-fast, highly scalable, and consistent access to
|
|
|
|
|
dynamic data sets. We solicit contributors.
