   Thanks! Sorry for the delay, I didn't see this review earlier.
   
   Some initial thoughts:
   
     1. Changing internal types of PCollections (e.g. PCollection<String> -> PCollection<BigQueryWriteResult>)
 in common transforms is something we try to avoid doing, as many users rely on being able
to in-place updates of their pipelines which is impossible when types change. Not a blocker,
we just might need to make the new behavior opt-in instead of the default.
   
    2. The set of load jobs generated is kind of an internal detail in BigQueryIO. It might
split an insert into multiple load jobs (and then run a copy job to merge them), or in the
case of streaming it might keep generating load jobs. In addition some of these load jobs
might simply be retry jobs for previously-failed load jobs. I'm not sure that outputting per
load-job information is going to give us what we want, when the logical model is per record.

> ATM BigQueryIO batchloads returns an empty collection that has no information related
to how the load job finished. It is even returned before the job finishes.
>  
> Change it so that:
>  # The returning PCollection only appers when the job has actually finished
>  # The returning PCollection contains information about the job result
