Kenneth Knowles updated BEAM-8172:
----------------------------------
Status: Open (was: Triage Needed)
> Add a label field to FunctionSpec proto
> ---------------------------------------
>
> Key: BEAM-8172
> URL: https://issues.apache.org/jira/browse/BEAM-8172
> Project: Beam
> Issue Type: Improvement
> Components: beam-model
> Reporter: Chad Dombrova
> Assignee: Chad Dombrova
> Priority: Major
>
> The FunctionSpec payload is opaque outside of the native environment, which
> can make debugging pipeline protos difficult. It would be very useful if the
> FunctionSpec had an optional human readable "label", for debugging and
> presenting in UIs and error messages.
> For example, in python, if the payload is an instance of a class, we could
> attempt to provide a string that represents the dotted path to that class,
> "mymodule.MyClass". In the case of coders, we could use the label to hold
> the type hint: "Optional[Iterable[mymodule.MyClass]]".
