### What would you like to happen? This seems to be supported/explained for Java/Python but not for Golang, for example in the SDF documentation > In Java, you can use [@UnboundedPerElement](https://beam.apache.org/releases/javadoc/current/index.html?org/apache/beam/sdk/transforms/DoFn.UnboundedPerElement.html) or [@BoundedPerElement](https://beam.apache.org/releases/javadoc/current/index.html?org/apache/beam/sdk/transforms/DoFn.BoundedPerElement.html) to annotate your DoFn. In Python, you can use [@unbounded_per_element](https://beam.apache.org/releases/pydoc/current/apache_beam.transforms.core.html#apache_beam.transforms.core.DoFn.unbounded_per_element) to annotate the DoFn. I think the right thing to do in Golang is implement `IsBounded() bool`, but it would be good to have that in the docs. It is also unclear how to have a regular, non-splittable, do Fn be unbounded if that is even possible. The pubsubio library uses `beam.External` which takes a `bounded` parameter, but I don't see any other examples of unbounded DoFns in golang. ### Issue Priority Priority: 3 (nice-to-have improvement) ### Issue Components - [ ] Component: Python SDK - [ ] Component: Java SDK - [X] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam YAML - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
