[jira] [Created] (BEAM-646) Get runners out of the apply()

Kenneth Knowles created BEAM-646:
------------------------------------

             Summary: Get runners out of the apply()
                 Key: BEAM-646
                 URL: https://issues.apache.org/jira/browse/BEAM-646
             Project: Beam
          Issue Type: Improvement
          Components: sdk-java-core
            Reporter: Kenneth Knowles
            Assignee: Thomas Groh


Right now, the runner intercepts calls to apply() and replaces transforms as we go. This means that there is no "original" user graph. For portability and misc architectural benefits, we would like to build the original graph first, and have the runner override later.

Some runners already work in this manner, but we could integrate it more smoothly, with more validation, via some handy APIs on e.g. the Pipeline object.
