RESTHeart Lacks MQTT Client Module for Broker-to-API Bridging
RESTHeart lacks a built-in MQTT client module to bridge external broker events to its HTTP, SSE, and MongoDB layers. Developers must build custom middleware to connect IoT message brokers with REST APIs.
MQTT Bridge Lacks Historical Replay From MongoDB via Last-Event-ID
An SSE-based MQTT bridge does not support replaying missed events when clients reconnect after a disconnect. The Last-Event-ID mechanism is not implemented, so clients lose messages during connection gaps.
MQTT Bridge Lacks WebSocket Endpoint for Browser Clients
An MQTT bridge only exposes topic subscriptions via SSE, which is unidirectional. Browser clients need WebSocket support for bidirectional communication with the MQTT broker.
MQTT Module Lacks Production Observability Metrics
MQTT ingestion module has no metrics for message rates, drops, buffer levels, or broker health, making production monitoring impossible.
