Designer guide Transformation icon legend

Stream icons

The icon in a node identifies its transformation family. Endpoint-backed Input and Sink nodes can replace the base icon with a transport-specific symbol.

When to use

Use this page while editing or reviewing the graph in the designer.

Behavior
