“解封"一个有上限的 MongoDB 集合 [英] "uncap" a capped MongoDB collection

问题描述

有没有办法解封"一个封顶的集合?创建新集合并复制数据对我来说不是一个选项.

is there a way to "uncap" a capped collection? Creating a new collection and copy the data isn't an option for me.

谢谢

推荐答案

不，您可以使用convertToCapped"命令将非封顶集合转换为封顶集合，但没有其他办法.

No, You can convert a non-capped collection to a capped collection using the "convertToCapped" command but there's no way to go the other way.

您唯一的选择是将集合克隆为无上限的集合并重命名，这显然会导致停机.

Your only option is to clone the collection to a non capped one and rename it which obviously involves downtime.
