The way to subscribe changes in realtime

[DCjanus]

My friend is trying to build a realtime and public dashboard for crates.io-index, to show some information to peopel, like how many crates release new version in the past 5 minutes.

That's why he is trying subscribe the changes from crates.io, there is a daily database dump from crates.io, which is really great, but which means we have to wait at most 24 hours to get updates, which made the dashboard not cool any more.

We was trying to subscribe the changes from GitHub API, via git diff on crates.io-index, which is really bother, since we have to handle variable situations, like git rebase, some unexpected changes, and so on.

And I do believe some people may want to get those data to create something fun, that would be really nice to find a way to publish changes in public.

The is just a green thought, since I've not found a good way to publish CDC in public, is there any idea from anyone else? If there is any way to resolve this, I'd like to contribute for it.
