   Please hold off on merging this for now. It sounds like Aryan is concerned
   that there may be an issue related to splitting.

> Currently, the BigQuery connector for reading data using the BigQuery Storage 
> API does not support any of the facilities on the source for Dataflow to 
> split streams.
>  
> On the server side, the BigQuery Storage API supports splitting streams at a 
> fraction. By adding support to the connector, we enable Dataflow to split 
> streams, which unlocks dynamic worker re-balancing.
