In general - no. You usually don't care about "stream", you care about the specific protocol that you are using on top of the tcp-or-other connection. And in general, nginx does not know the details of *that* protocol. In specific cases - maybe. What is the use case that you care about here? > How nginx persist tcp connection with downstream? It's a tcp connection. From ip:port to ip:port at time, and subsequent packets refer to previous ones. The tcp connection stays active until it gets closed - Reset or Fin, usually. > How nginx persist tcp connection with upstream? Same answer, unless you have a specific use-case that wants further explanation, I think. > What is the "session" meaning in the stream context? Where do you see that term? Possibly the context there, will provide the description? I see http://nginx.org/en/docs/njs/reference.html#stream and http://nginx.org/en/docs/stream/ngx_stream_upstream_module.html#var_upstream_session_time and some mentions in http://nginx.org/en/docs/stream/ngx_stream_proxy_module.html Generally, they seem to refer to "what you would expect they refer to". All of the exact what-nginx-does "documentation" is in the src/stream/ directory. The more general "summary" docs are at the website links above. If you can point at a piece of documentation that should describe what you want but does not, that will be useful information to help someone improve the documentation.
