[Starlingx-discuss] [Neutron] Question on uwsgi based web server support for neutron
Miguel, During STX deployment process, it is found the current neutron eventlet based web server has some unexpected behavior for multiple long live clients and it is also verified that apache WSGI/uwsgi based web server can solve such issues. the detail information of this issue can be found at https://bugs.launchpad.net/neutron/+bug/1800599. So is there any plan or roadmap to switch to the new apache WSGI/uswgi based web server for Neutron in Stein release? Thanks much! Best Regards, Le, Huifeng

AFAIK it is already possible since Rocky https://docs.openstack.org/neutron/rocky/admin/config-wsgi.html Is it what You are asking for?

Slawek, Thanks much for the information. Yes, it is already possible to configure using uswgi for neutron API which is also the way I used to verify the issue. So will it be used as default configuration (as other openstack projects) for neutron in any planned release? or it supposed to require the system admin to apply this configuration manually when deployment? thanks much!

Hi, I don’t know about any plans to make it default now in Stein. IMO We can think about it in Train cycle.

that said i do think that more project should consider moving to wsgi only. eventually i would hope we could drop all eventlet depencies in openstack but i know that for several of the agents like the nova agent that is hard to do. for the apis however wsgi provided a convent way to drop that depency and improve performance at the same time.

Hi, I’m not sure but probably, if this would require any changes in neutron code, then it should be proposed as RFE and discussed by drivers team.
