Add SO_REUSEPORT support to socket. Introduce new feature for Twemproxy running on newer kernels. With this feature you are able to do upgrades, restarts without any downtime. Kernel does load balancing between processes with the same host:port pairs.

@ton31337 twemproxy can run on mac or freebsd also. so I think you should check other os too not only linux :)

@charsyam 👍 of course will fix this, but need to be sure if it's worth to spend more time. I mean if it's planned to be merged or not.

Introduce new feature for Twemproxy running on newer kernels. With this
feature you are able to do upgrades, restarts without any downtime. Kernel
does load balancing between processes with the same host:port pairs.

Also, helps running on more than single core.

This seems to work locally - testing since I haven't used SO_REUSEPORT elsewhere. I can start two nutcracker instances for memcached with reuseport: true and

  • stats ports are shared and go to one of the two instances (unrelated to the config file setting for individual pools)
  • New connections are shared and go to one of the two instances
  • Connections stay connected to the same instance
