Python SDK dbxquery results limited to 100k rows using jobs.export- Do I need to paginate streaming results?

[joecav]

Running a dbxquery through jobs.export my results are limited to 100k rows. Do I need to paginate streaming results? 

Here's my code:

data = {
        'adhoc_search_level': 'fast',
        'search_mode': 'normal',
        'preview': False,
        'max_count': 500000,
        'output_mode': 'json',
        'auto_cancel': 300,
        'count': 0
    }

job = service.jobs.export(<dbxquery>, **data)
reader = results.JSONResultsReader(job)
lst = [result for result in reader if isinstance(result, dict)]

This runs correctly except that that results are always stopped at 100k rows, it should be over 200k.
