Since many of you have shown interest in the planned ‘hierarchical streams’ feature in the SDK, I wanted to post back my latest summary from that thread. We are getting nearer to spec which we can move forward on and I’d welcome feedback here in the issue: https://gitlab.com/meltano/singer-sdk/-/issues/97#note_552981324 In the meanwhile, as I mentioned in my comment to @hassan_syyid here, the workaround available today is to explicitly declare the parent items the

Streams.partitions

property of the child class.
