Time-series IoT tracker using QuestDB, Node.js, and Grafana

QuestDB is an open-source time-series database designed for high-performance workloads, offering ultra-low latency, high ingestion throughput, and a multi-tier storage engine with native support for Parquet and SQL, ensuring data portability and AI-readiness without vendor lock-in. The tutorial demonstrates how to use QuestDB to efficiently ingest and analyze real-time IoT data by setting up a Node.js IoT simulator to generate data, storing it in QuestDB, and visualizing it with Grafana. Utilizing the InfluxDB Line Protocol for data transmission, QuestDB efficiently handles large volumes and high cardinality of time-series data, with features like data deduplication and out-of-order indexing. The process involves using Docker Compose to set up QuestDB and Grafana, where the latter is used for advanced data visualization. The tutorial illustrates the speed and efficiency of QuestDB in managing and visualizing bursting data, highlighting its advantages over traditional databases in handling time-series data, and offering insights into potential real-world applications with managed IoT services.
