About Nodes

A node serves as the fundamental building block of a workflow. It completes a processing step by receiving input variables, executing its programe, and producing output variables.

The output results of a node can be passed to downstream nodes for further processing or directly transmitted to the End node as the final output of the workflow.

A workflow is formed by interconnecting multiple nodes, establishing upstream and downstream relationships between them.

Run

graph LR I[Input (Variable Definitions)] R[Configuration & Run] O[Output] I --> R --> O

Each node follows an "Input, Run, Output" structure, which can be conceptualized as a function.

Input (Variable Definition)

This section defines the variables required for the node's operation. These defined variables can be embedded into configration items.

Configuration & Run

This section allows you to configure the specific execution logic of the node.

Variables defined in the current node can be embedded into configuration items.

Output

This section allows you to define the output structure and variables of the node, enabling downstream nodes to receive and utilize them. Output fields and values can be mapped to the input variables of the subsequent nodes.

Note: The output structure and variables vary depending on the component type.
