Input Dataset

Overview

Input Dataset is an important upstream operator in a Dataflow Node. It serves as the starting point of the ETL process and provides the data foundation for the extraction stage and subsequent ETL processing.

It supports fast integration of heterogeneous multi-source data through multiple inputs, making it easy to combine data from different sources and structures.

Procedure

1. Drag the Input Dataset operator from the dataflow operator panel into the canvas on the right.

   

2. Click the Input Dataset operator and choose the target dataset.

   

3. Click Confirm to upload the dataset.

4. Optionally configure preview rules for the input dataset as needed.

   

5. You can then add other operator nodes to build a complete data processing workflow.
