I dusted off an implementation of MQTT for SWI-Prolog so the way I did all the integration was via MQTT messages between Java. Python, c/c++ (on Arduino devices), and Prolog.

These days SWI-Prolog even has a library for Redis.

For Go, you have prolog as a scripting engine https://github.com/ichiban/prolog
