Thanks for the PR.

I feel like I am missing something. It's not clear to me why we need a separate "streaming client" writer, could we not do it from the existing client?

But more importantly, I think the overall approach we had taken when we extended the plugin contract with "archive" storage was to add Capabilities field that tells the client if the plugin implementation supports additional interfaces. So I am surprised that you don't have any changed to the Factory files.

Lastly, I would like to have integration tests to exercise the new functionality.

lgtm overall, I kicked off the tests
