Question

使用文档中的示例：

>>> rev_with_d = users.query_2(
...     account_type__eq='standard_user',
...     last_name__beginswith='D',
...     reverse=True,
...     limit=2
... )

>>> for user in rev_with_d:
...     print user['first_name']
'John'
'Jane'

在这种情况下如何处理吞吐量异常？

我已尝试在每个循环中使用指数退避，但异常不会被捕获。

我认为您最好设置max_page_size的{{1}}参数。
您应该设置一个基于表的读取吞吐量和项目大小的值。
