Thyne: Real-Time Synchronization for IoT Medical Dashboards

A next-generation health-tech platform struggled with data synchronization latency between IoT medical devices and clinician dashboards. Vital telemetry packets were delayed, meaning doctors saw critical patient updates with latency.

We refactored their synchronization layer using event-driven WebSockets and optimized PostgreSQL write paths to guarantee real-time delivery.

Key Challenges

1. PostgreSQL Lock Contention

Telemetry records were batch-inserted into a single table. Under high device density, index updates locked the table, delaying incoming writes.

2. Dashboards Polling Latency

Clinician frontends polled the REST API every 4 seconds, meaning data was out-of-date before the next poll.

Solutions Implemented

Event-Driven WebSockets

We built a WebSocket relay cluster that distributes real-time patient vitals directly from devices to frontend dashboards.

Database Partitioning

We introduced monthly database partitioning on the telemetry log table to maintain constant index heights and high write speeds.

Real-Time Validation

We benchmarked the system under 50,000 simulated devices, confirming latency remained under 120ms.
