      Work Description: mxm commented on issue #11052: [BEAM-9446] Add missing 
parallelism and execution mode args.
URL: https://github.com/apache/beam/pull/11052#issuecomment-598434409
 
 
   What I meant is keeping "unknown" pipeline options instead of discarding 
them. If we pass the unknown ones as strings I thought this could work. For 
example, if we pass `"123"` the parser on the Java side is smart enough to 
figure it is the integer `123`. I haven't tried this out but I'd suggest we do.
   
   Of course this is not very user-friendly. That's why I'd suggest to write 
pipeline options in a language-agnostic format which can be read by all SDKs.
   
   Considering the Flink pipeline options, what we usually want to set is what 
is called `ExecutionConfig` in Flink. With Flink they are configured directly 
in the API. For Beam if the parameters are just strings/ints we could come up 
with something reflection based to set arbitrary new settings. I agree this 
would be helpful.

> I need these options for TFX, but they're being discarded (I believe they are
