Facebook Python SDK 中异步作业的限制是多少？

Question

I'm creating an async job with Facebook's Python SDK to get the insights (impressions, action_values, etc) for my Facebook campaigns. Right now I'd like to pull all the campaigns for the previous year by month. The total number of results should be around 2,000 . If I set the limit param in get_result to anything higher than 1000 I get a FacebookRequestError . The async_job

(see code below) runs, and using

api_get()

I can tell that it pulls all the records. Is there anyway to pull all of the results from the async_job ?

async_job = my_account.get_insights_async(fields=params.get('fields'), params=params)
async_job.api_get(
while async_job.api_get()['async_percent_completion'] < 100:
  time.sleep(1)
  async_job.api_get() 
data = async_job.get_result(params={'limit':1000})
