Question

我在debian 8 64位实例上设置了couchdb。

当我查询其中一个视图时，它会从卷曲的角度来看超时。

以下是我看到的形式couch.log：

                        {links,[<0.95.0>]},

一些沙发专家可以帮我解决这个问题吗？

请注意，如果reduce函数的结果长于初始值列表，则会引发Query Server错误。但是，可以通过将reduce_limit config选项设置为false来禁用此行为

http://docs.couchdb.org/en/latest/couchapp/ddocs.html

在页面中搜索reduce_limit的出现次数。
