TDengine

TDengine

TDengine is a distributed time-series database designed for the high-speed ingestion, compression, and retrieval of timestamped metrics and sensor data. It functions as a SQL-compatible analytics engine, allowing users to perform complex operations on massive volumes of time-ordered information using standard relational syntax. The platform is built to serve as a backend foundation for industrial IoT environments, managing real-time data streams and device metadata through a cluster-based architecture.

The system distinguishes itself through a distributed sharding architecture that uses consistent hashing to ensure horizontal scalability and high-throughput ingestion. It employs a log-structured write path to minimize disk seek latency and utilizes super-table virtualization to provide a unified logical view across multiple physical tables. To maintain performance and cost-efficiency, the database features automated multi-tiered lifecycle management, which migrates data between high-performance memory and low-cost storage based on age and access frequency.

Beyond its core storage capabilities, the platform provides robust tools for edge-to-cloud synchronization, ensuring consistent data states across geographically distributed infrastructure. It includes built-in support for real-time stream processing, allowing for the analysis of live data without requiring external message queues. The system also incorporates comprehensive security frameworks, including user access control, audit logging, and encrypted transport protocols to protect sensitive operational data.

Developers can interact with the database through native client libraries that support connection pooling and query parameter binding. The system is documented with comprehensive error code diagnostics and provides command-line utilities for cluster administration, health monitoring, and configuration management.
