> DoFnLifeCycleManager should hold DoFnInvoker, not DoFn/OldDoFn
> --------------------------------------------------------------

> Key: BEAM-800

> Project: Beam
> Issue Type: Bug
> Components: runner-direct
> Reporter: Kenneth Knowles

> Priority: Minor
> Fix For: Not applicable
>
>
> 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.
