resource downloads to agents not throttled

[Ian Booth]

Many charms may simultaneously perform a resource-get to fetch a resource blob.
This request goes via the controller which acts as a caching proxy to charmhub.

Bug 1905703 addressed the situation where the controller would attempt to download the same blob from charmhub at the same time if many requests all came in together.

What is not addressed though is that the controller does not throttle serving resource blobs to unit agents. It's possible to DOS the controller and/or flood the network bandwidth if too many concurrent requests are served.

Hello,

Does anyone know the status of this?

Thanks

There's been no work on this since the work to throttle the charmhub requests.
I'll move to a release milestone to give it a bit more visibility.
