Make use of Unix Domain Sockets in Netty (using the NIO transport) by mkurz · Pull Request #13222 · playframework/playframework
Low priority, just pushing what I was playing around with.
Currently this is not working, because we run into an java.nio.channels.UnsupportedAddressTypeException.
That is because we use the NioServerDomainSocketChannel which expects we are working with sockets (= file path), but we pass an inet address (host:port).
