support deletes

[kevmo314]

Right now the CDN doesn't support deleting nodes. This is a bit tricky because child subscribers need to resubscribe somewhere else, but if we can figure out a solution for deleting nodes then we can deploy on preemptible instances.

Just out of curiosity, under what circumstance would we be deleting parent nodes?

We don't actually have to support deletes, we could run our entire CDN without explicit node deletion. But if we manage to get it working, it means we can use preemptible instances to proxy traffic and those save 70%+ in costs so the CDN would be substantially cheaper to run.

For mvp it's not really necessary though :)

got it. So this will be an auto scaling feature to accommodate usage fluctuations once we get to a certain size.

Yup exactly. There is some engineering elegance to it though, since adding it would make the CDN "complete". But it's similar to tree rebalancing, not strictly necessary just kind of cool.

🤓🤓, Coolness is what we are about 😎
