TDengine
AI-powered time-series database for Industrial IoT
About TDengine
TDengine is a high-performance time-series database built for Industrial IoT, connected vehicles, and large-scale sensor data workloads. It combines a time-series database engine with built-in stream processing, caching, data subscription, and an AI copilot for anomaly detection and forecasting. Available as open-source, self-hosted enterprise, and fully managed TDengine Cloud on AWS, Azure, and GCP.
Pros & Cons
Pros
- Exceptional write throughput and query speed — benchmarks show up to 426x faster queries than InfluxDB
- All-in-one platform eliminates separate message queue, cache, stream processor, and TSDB
- Up to 12x storage savings through columnar compression optimized for time-series data
- Native SQL support minimizes learning curve for relational database teams
- Industrial-grade connectors for OPC-UA, PI System, and MQTT out of the box
- Open-source core allows free evaluation and small deployments
Cons
- Cloud pricing starts at \u0024975/month — expensive for small teams or early-stage projects
- Optimized specifically for time-series data — not suitable for general-purpose workloads
- Smaller community than InfluxDB or TimescaleDB with fewer third-party resources
- Industrial data modeling concepts require OT domain knowledge
- Admin dashboard UI reported as less polished than competitors
- Documentation gaps in edge-case configurations and advanced tuning
