[GitHub] [beam] kennknowles opened a new issue, #18587: Fn Execution APIs should not depend on the Java SDK

[GitBox <gi...@apache.org>]

kennknowles opened a new issue, #18587:
URL: https://github.com/apache/beam/issues/18587

   Runners should be able to interact with the Fn API with complete ignorance of the underlying SDK, and as such should not obtain a dependency on the Java SDK.
   
   This dependency edge should be banned. This will also require moving shared model abstractions which require code execution to a module on which both fn execution APIs and the Java SDK can depend on.
   
   NOTE: the current state of this change requires either factoring of Coder, BoundedWindow, and associated runner-relevant code to a common location. Currently, these dependency edges exist to reduce work required to encode and decode these elements and minimize duplication between the runner and SDK for model-level concepts.
