# ADK Workflow Routing Sample
|
|
|
|
## Overview
|
|
|
|
This sample demonstrates how to use routing in **ADK Workflows**.
|
|
|
|
It takes user input and uses an LLM node to categorize it as a **question**, a **statement**, or **other**. Based on the classification, it appropriately routes the execution to a specialized agent or function to handle that specific type of input.
|
|
|
|
In ADK Workflows, **routing** allows conditionally executing different execution paths based on the output of a previous node.
|
|
|
|
## Sample Inputs
|
|
|
|
- `What is the capital of France?`
|
|
|
|
- `The weather is very nice today.`
|
|
|
|
- `Translate bonjour to english`
|
|
|
|

|
|
route_on_category -->|other| handle_other
|
|
```
|
|
|
|
## How To
|
|
|
|
1. A node (agent or function) yields an `Event` with a specific route name:
|
|
|
|
```python
|
|
yield Event(route="your_route_name")
|
|
```
|
|
|
|
1. In the `Workflow` edges definition, conditional edges are constructed using a routing map dict as the second element of the edge tuple:
|
|
|
|
```python
|
|
(source_node, {"your_route_name": target_node})
|
|
```
