Thanks for sharing your writeup and the potential use cases therein.

We've been building an experimental shared file system that specifically targets the FaaS setting. It supports SQLite and gets big performance gains over NFS/EFS, especially on read-mostly workloads, due to improved local caching and lock elision. See: https://arxiv.org/abs/2009.09845

Really interesting.

How do you deal with ephemeral file storage? I guess you actually need the provider (say AWS) to build this into the platform?

Yes, the idea is that the cloud provider should offer something like this. We intercepted system calls to simulate what it would look like.
