[jira] [Commented] (BEAM-2717) Infer coders in SDK prior to handing off pipeline to Runner

    [ https://issues.apache.org/jira/browse/BEAM-2717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17061250#comment-17061250 ] 

Joao Peixoto commented on BEAM-2717:
------------------------------------

Ran into this issue while trying to deploy a pipeline into GCP.

I'm not sure I understand what the underlying problem is or how to work around it. Could someone shed some light?

My pipeline uses protobuf to generate the types used within. Classes and functions are annotated with "@beam.typehints.with_input_types" and the like.

> Currently all runners have to duplicate this work, and there's also a hack storing the element type rather than the coder in the Runner protos.
