             Summary: Add support for ExtensionRegistry with PTypes.protos
                 Key: CRUNCH-328
                 URL: https://issues.apache.org/jira/browse/CRUNCH-328
             Project: Crunch
          Issue Type: Bug
          Components: Core
            Reporter: Josh Wills
            Assignee: Josh Wills


Came across a use case where it would be great to be able to have support for deserializing protobufs using an ExtensionRegistry for some custom message extensions. ExtensionRegistry isn't serializable and there isn't a good way to serialize it using the current protobuf libraries, so I also created a Serializable extension of Guava's Supplier interface to handle cases where we need to specify how to construct an object for use in a DoFn as an external argument, which seemed fairly useful.
