Sources

Sources are nodes that bring data into the workflow. They typically do not require an incoming connection from another node; instead they go out to an external system or accept input from the user and produce an output (a DataFrame or a file) that downstream nodes can use.

Sources include nodes that query a database (Visual Query, Query), import tabular data from files (CSV, Excel, JSON, Parquet), read files from storage locations (B2Win Suite server, WinShare, SharePoint, IDM), upload a file from the user's machine (File Uploader), and call an external OpenAPI endpoint (Invoke OpenAPI, Invoke OpenAPI Input).
