Danube Messaging v0.14.0: Edge Mode for MQTT to Cloud IoT Ingestion
Danube is an open-source distributed messaging platform built in Rust with embedded Raft consensus and zero external dependencies.
v0.14.0 introduces a third deployment mode: Edge. The broker now runs as:
- Standalone: single node, zero config, for development
- Cluster: multi-broker with Raft, leader election, and automated rebalancing
- Edge: lightweight MQTT gateway (v3.1.1/v5.0) that ingests IoT device data, validates payloads against schemas from the cluster registry, buffers into a local WAL, and continuously replicates to the central cluster
