TDengine is an open-source, purpose-built time-series database designed for the massive data volumes and high-speed requirements of the Internet of Things (IoT). Unlike general-purpose time-series databases, TDengine provides an all-in-one solution that includes caching, stream processing, and event-driven data handling, significantly reducing the complexity of IoT architectures.
It is engineered to handle massive numbers of data sources (meters, sensors, or devices) and provides a unique "one-table-per-device" modeling approach that ensures high-speed ingestion and instant querying even under heavy load. By collapsing multiple layers of the typical IoT backend into a single system, TDengine helps organizations lower their total cost of ownership and accelerate deployment.
Self-hosting TDengine gives industrial and infrastructure teams the performance and reliability needed for mission-critical monitoring while keeping sensitive operational data local and secure.
Key Benefits
- Extreme Throughput: Ingest millions of items per second on a single instance.
- Simplified Stack: Replace Redis, Kafka, and the database with one TDengine cluster.
- Cost Efficient: Drastic reduction in cloud storage and CPU costs compared to InfluxDB or Timescale.
- Developer Friendly: Use standard SQL for everything—no complex new query languages to learn.
- Cloud-Native Resilience: Built to run on Kubernetes with automated failover and scaling.
Production Architecture Overview
A production TDengine (v3.0+) cluster consists of:
- dnodes (Data Nodes): Handle data storage, query processing, and management.
- mnodes (Management Nodes): Manage cluster metadata and node status (distributed).
- qnodes (Query Nodes): Dedicated compute resources for complex aggregations.
- Load Balancer: Standard TCP/HTTP load balancer to distribute client requests.
- Persistent Storage: Local high-speed NVMe/SSD for hot data and HDD/S3 for archival.

Deploy using the official TDengine Helm chart for high-availability clusters.
helm repo add tdengine https://helm.tdengine.com
helm install tdengine tdengine/tdengine --namespace iot-system --create-namespaceBenefits:
- StatefulSet Management: Guarantees pod identity and stable storage for dnodes.
- Automatic Scaling: Increase dnode replicas as your device count grows.
- Persistent Volume Claims: Automatically attach high-speed cloud storage to your database nodes.
Scaling Strategy
- Increase vnodes: Adjust the number of virtual nodes (vnodes) per dnode to maximize CPU utilization.
- Separate Management Nodes: In large clusters, run mnodes on dedicated, isolated pods.
- Tiered Storage: Use TDengine's tiered storage configuration to move data older than 30 days to S3-compatible object storage.
Reliability & Monitoring
- Raft Redundancy: Configure at least three replicas for critical data to ensure continuous operation during node failure.
- Grafana Integration: Use the official TDengine Grafana plugin for real-time operational dashboards.
- Backup Tool: Use
taosdumpfor full and incremental logical backups of individual databases or the entire cluster.
