## Experimental Features

**⚠️ Note: Experimental features and their behavior may change in future versions.**

### Code Attributes

Code attributes is an experimental feature that automatically captures source code context information when trace data is generated. This feature enhances observability by providing precise code-level details that help developers quickly identify and debug issues.

Code attributes capture:
* **Source file path** - The exact file where the telemetry originated
* **Function name** - The method or function fully-qualified name, including class/namespace context when applicable (e.g., `com.example.MyService.processRequest`, `MyClass.my_method`)
* **Line numbers** - Precise code location for pinpoint debugging

To enable code attributes, set the following environment variable:
```bash
export OTEL_AWS_EXPERIMENTAL_CODE_ATTRIBUTES=true
```
