Scaling DDS and MQTT with Eclipse Zenoh
summary
Eclipse Zenoh claims to bridge DDS and MQTT without code changes by running as a router plugin or standalone bridge, handing DDS mirror readers/writers and an MQTT broker interface; demo ties a Zigbee button on a Raspberry Pi to robots via the bridges and works live. Zenoh runs on microcontrollers (Rust core plus C subset), supports TCP/UDP/serial, syncs distributed storage, and reports up to 70 Gbps on 100 GbE and 5 μs inter‑host latency.
