[Andrew Svetlov]

Andrew Svetlov  added the comment:

For server applications, the reverse proxy in front of the application can 
limit the connection limit.
It is a good workaround because the proxy is required (and most likely is used 
already) for any non-trivial server app.

Hi Yury, no, I'm not familiar with the other frameworks (libuv doesn't have 
this). I'll need to look into it. If anybody else knows, please comment as well.

Do other frameworks (Tornado, Twisted, libuv/nodejs) have this functionality?

[issue33840] connection limit on listening socket in asyncio

[Lisa Guo]

New submission from Lisa Guo :

I'd like to re-open the discussion on pause_server/resume_server that's been 
discussed here:

https://groups.google.com/forum/?utm_source=digest_medium=email#!topic/python-tulip/btGHbh5kUUM

with PR:

https://github.com/python/asyncio/pull/448

We would like to set a max_connection parameters to a listening socket. 
Whenever it reaches this number with open accepted sockets, it stops accepting 
new connections until a user request is served, response sent back, and the 
connection closed. This is useful for a web application where the more user 
requests accepted and processed in-flight isn't necessarily better for 
performance. It would be great if we could dynamically change this value as 
well.

Some more detailed behavior:

- it can be either a per loop parameter, or per server parameter
- the number of currently open accepted connections is counted against this 
limit
- if max connection is reached, remove the listening socket from the loop so it 
back pressures new connections to kernel and other processes can take them
- when total number of accepted connections drops below max connection, put the 
listening socket back in the loop
- it can be dynamically configured but has no effect on currently already 
accepted connections (useful for graceful shutdown)
