Build Read Components
Read Components are the starting points of your data pipelines. They connect Ascend to various data sources and bring data into your Data Plane for processing. This section provides step-by-step guides for building Read Components for different types of data sources.
Before you begin
- Ensure you have an Ascend Project and Workspace
- Set up the appropriate Connection for your data source
