From MQTT to SQL: A Practical Guide to Sensor Data Ingestion

Per-message SQL inserts fail at scale because MQTT streams clash with transactional databases. This guide shows how time-window batching, TimescaleDB hypertables, and the COPY protocol enable high-throughput ingestion. It covers deduplication, graceful shutdown, error recovery, and back-pressure strategies—turning fragile IoT pipelines into reliable, production-ready systems.
