Hi! Are there any plans to include azure storage as an external cache? Is there perhaps a technical reason Google and AWS storage services are supported but Azure is not?

Thanks!

Hey there.

I’ll do some experimenting and will let you know.

Hey,

unfortunately Azure is not supported due to the way that we currently detect changes in external files (ETag).

Fixing this would requires some changes, which have been discussed in the past (see for example this discussion: [external workspaces · Issue #3920 · iterative/dvc · GitHub](https://github.com/iterative/dvc/issues/3920)), but for which nothing has been planned yet.
