Nice one re: flatbuffers in `blob` column. Have been working with flatbuffers a lot and that's a neat idea in general. Not 100% sure about using PG for file system at scale however. I'd love to hear more on the challenges (vacuum,

v interesting. Thanks for sharing. I kept seeing this phenomenon of "no free lunches". TIL about the waterbed theory.

that's very interesting! I was noticing page vault storm on live migrations as well and I wonder if that's what you were running into / mentioning here regarding the lock contention

Cool project. +1 on userfaultfd for the multi-node path. Wrote about how uffd-based on-demand restore works wrt to my Cloud Hypervisor change [1] if you are curious. I think the the main things to watch are fault storms at resume (all vCPUs

That's a good shout. I will update/port it back from here - https://github.com/cloud-hypervisor/cloud-hypervisor/pull/78... , but quite fast

This is going to be an interesting space to watch I think and big part of offering sandbox as a service basically for enterprise and saas needs.

Yeah, it's hard to hit the right balance with nuance around these and you're spot on. What I meant to get at was the specific difference in default modes where gVisor's systrap intercepts syscalls via seccomp traps and handle

Heya! nice to see you here. In retrospect it feels like CI companies and environments are very well suited for sandboxes since a lot of the problems overlap around ephemeral workloads, running untrusted code, fast cold starts, multi-tenancy

It touches in the gvisor section around the trade-off that the surface area for gvisor is smaller. There are trade offs. It’s not dishonest.

That’s a good shout! I have been curious as well and did some experiments. Also left out GPU sandboxing from the post as well. Maybe will reflect in a part II post.

That is a good call out and I missed to consider the options you pointed. When I am back on keyboard I will add an updated note with a link to your comment. Thank you!
