GRPC: A high performance, open source, general RPC framework

Presuming you've done the research here: will Websocket-over-HTTP2 make websockets cheaper, to the point that e.g. it'd be performant to use individual websockets for each channel of a pub-sub system, rather than multiplexing them all over a single channel that is statefully subscribed on the server?

Or, now that I think of it, would the modern recommendation for this lean more toward opening multiple parallel Server-Sent-Events streams, with each channel being its own HTTP resource? That seems more idiomatic, at least.

That is certainly a goal for Websocket-over-HTTP2, though in truth it would be no cheaper than long-poll-over-HTTP2 and more expensive if you invented your own metadata mechanism rather than using HTTP2 headers. And as you say, less idiomatic.

Using separately addressable resources and having HTTP2 do the connection multiplexing for you seems like a good pattern to me.
