> Dataflow Java runner uses 0.1 secs interval for polling bundle progress from 
> SDK Harness, and use the result to decide whether data transfer should be 
> throttled. This can potentially overload SDK Harness. 
> We should try to come up with a way to avoid the throttling and lower the 
> bundle progress request frequency significantly.
