> Now, the JDBC IO is basically a {{DoFn}} executed with a {{ParDo}}. So, it means that
parallelism is "limited" and executed on one executor.
> We can imagine to create several JDBC {{BoundedSource}}s splitting the SQL query in 
subset (for instance using row id paging or any "splitting/limit" we can figure based on the
original SQL query) (something similar to what Sqoop is doing).
