> {{BigQueryIO.Write}} right now requires that the table schema be known at 
> pipeline construction time. There are two feature requests:
> 1. It should be possible to operate in some modes (where table is not 
> created, but only appended-to or truncated) where the schema need not be 
> known at construction time.
> 2. It might be possible to operate in such a way that tables are created at 
> runtime using a schema that is determined dynamically at runtime. We would 
> possibly need the schema sent as a side input.
