> ATM `BigQuerySource` in Python SDK can only be used by Dataflow runner. Because of this it's impossible to read data from BigQuery on portable runners, such as Flink.
>  
> The goal is to add a transform, that follows BQ source implementation in Java[1]: use a BigQuery export job to take a snapshot of the table on GCS, and then read from each produced file.
