BigQuery async query job - the fetch_results() method returns wrong number of values

Question

I am writing Python code with the BigQuery Client API, and attempting to use the async query code (written everywhere as a code sample), and it is failing at the fetch_data(

Looks like you are right! The code no longer return these 3 parameters.

As you can see in this commit from the public repository, fetch_data now returns an instance of the HTTPIterator class (guess I didn't realize this before as I have a docker image with an older version of the bigquery client installed where it does return the 3 values).

The only way that I found to return the results was doing something like this:

iterator = job_results.fetch_data()
data = []
for page in iterator._page_iter(False):
    data.extend([page.next() for i in range(page.num_items)])

Notice that now we don't have to manage pageTokens anymore, it's been automated for the most part.

[EDIT]:

I just realized you can get results by doing:

results = list(job_results.fetch_data())

Got to admit it's way easier now then it was before!
