<!-- code-pr-reviewer --> Based on the source code analysis, TDengine Source connector only supports **batch mode**, not streaming: - `TDengineSource.java:82-84` returns `Boundedness.BOUNDED`, meaning it reads data once and finishes - Official docs (`docs/en/connectors/source/TDengine.md`) confirm this: stream feature is unchecked - `scan_interval`, `start_mode`, and `timestamp_column` are **not valid** TDengine connector options (see `TDengineSourceOptions.java`) To achieve continuous incremental sync, you can: - Use an external scheduler (Airflow/DolphinScheduler) to run batch jobs periodically with updated `lower_bound`/`upper_bound` - Leverage TDengine's subscription feature with other streaming tools Regarding InfluxDB: it also **does not support streaming** (`InfluxDBSource.java:70-72` returns `BOUNDED`). For true streaming CDC, consider connectors like MySQL CDC or Postgres CDC instead. -- This is an automated message from the Apache Git Service.
