Subject [jira] [Created] (BEAM-800) DoFnLifeCycleManager should hold DoFnInvoker, not DoFn/OldDoFn
Date Sun, 23 Oct 2016 21:33:58 GMT
Kenneth Knowles created BEAM-800:
------------------------------------

             Summary: DoFnLifeCycleManager should hold DoFnInvoker, not DoFn/OldDoFn
                 Key: BEAM-800
                 URL: https://issues.apache.org/jira/browse/BEAM-800
             Project: Beam
          Issue Type: Bug
          Components: runner-direct
            Reporter: Kenneth Knowles
            Priority: Minor


The {{DirectRunner}}'s support class {{DoFnLifecycleManager}} holds a cache of deserialized
{{OldDoFn}}s, now being ported to {{DoFn}}s. But to execute a {{DoFn}} there is another layer
of indirection through a {{DoFnInvoker}}, which is the best object to cache here.
