Manu Zhang updated BEAM-800:
----------------------------
Description: 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. (was: 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.)
> DoFnLifeCycleManager should hold DoFnInvoker, not DoFn/OldDoFn
