From delayed polling to Real-Time Telematics with RabbitMQ and Erlang
summary
Lucid Logistics replaces slow polling with a PubSubHubbub-style pipeline built on RabbitMQ and Erlang using the rabbit_hub plugin to push SBD telemetry (10–20 byte messages over Aridium SBD) via HTTPS to customer callbacks, adds durable queues and message persistence so data survives restarts, and moves parsing into Rabbit queues; latencies drop from minutes under polling to milliseconds in typical operation and single-message satellite delivery is often under 30 seconds, proving the approach works in production.
