Advanced Features

This section describes the advanced features of TDengine, including data subscription, caching, and stream processing; edge–cloud orchestration; and connectors for various data sources.

📄️ Data Subscription

TDengine provides Kafka-like publish/subscribe data subscription as a built-in component. You create topics in TDengine using SQL statements, and your applications can subscribe to your topics as consumers.

📄️ Caching

TDengine includes caching as a built-in component. This includes write caching, read caching, metadata caching, and file system caching.

📄️ Stream Processing

TDengine includes stream processing as a built-in component. You define real-time stream transformations by using SQL statements. Data written to the source table of the stream is then automatically processed in the specified manner and written to the target supertable based on the specified trigger mode. This provides a lightweight alternative to complex stream processing systems while delivering results in milliseconds even under high-throughput conditions.
