当我尝试以excel格式下载记录时，我在浏览器中收到504 Gateway Timeout错误消息。在我对此进行调查时，查询执行时间过长会出现超时问题。因此，我已将unicorn worker超时值更改为240（即使我测试了1000+）和nginx proxy _ * _ timeout值从300更改为600.但是，再次失败。
我的实现是将用户详细信息导出为excel格式，但我只是在运行中计算所有内容。应该运行四个查询来导出单个记录。所以，我尝试8000条记录进行测试。
8000（记录）* 4（查询）= 32000次查询
如果您有任何其他想法在excel中导出长期查询结果，请告诉我。 THX。
PFB用于配置和错误详情。
