We now support Redis connections using OS-native transports through unix domain sockets when using the Lettuce driver. Domain sockets do not require a roundtrip through the networking layer but directly use native epoll or kqueue interfaces.
LettuceConnectionFactory factory = new LettuceConnectionFactory(new RedisSocketConfiguration("/var/run/redis.sock"));
Unix domain socket support requires netty's native epoll/kqueue dependencies matching the runtime environment:
