Efficient user-space threads (go routines) and the way go lends itself to the reactor pattern is exactly why is has been the language of choice for the company I work for. We use it to power all of our distributed microservices which process IoT packets from a stream. The performance and ease-of-use is heads and shoulders above everything else we tried before (mainly, Java with Kafka/Storm).
