持续寿命 [英] Persistence lifetime

问题描述

我读了几篇有关IndexdDB的文章，但是找不到有关持久化数据生存期的详细信息.我计划将其用于数据操作会话，并在用户完成操作后上传.但是，如果发生以下情况，将会发生什么事?

I read few articles about IndexdDB, but couldn't find details about the lifetime of persisted data. I plan to use it for a session of data manipulation and upload once the user finishes. But what will happen if:

• 用户关闭浏览器标签
• 用户关闭浏览器
• 用户重新启动系统

另外， 我通过基于cookie的身份验证来维护用户会话.如果用户注销并再次登录，将会发生什么?是否可以在注销之前检索数据?

Also, I maintain user session through cookie based authentication. What will happen if the user logs off and log back in again? Is there a way to retrieve the data before the logoff?

任何有关处理此问题的文档都将受到赞赏.我浏览了规范，但是阅读起来并不好.

Any documentation on handling this is appreciated. I skimmed through the spec, but it is not that good a read.

谢谢.

推荐答案

IndexedDB数据属于类型暂时的.因此可以随时清除这些数据.

IndexedDB data belong to a type of temporary. So these data can be wiped out at any time.

这些数据大小/寿命由非常新的配额管理API 进行管理.

These data size/lifetime are managed by very new Quota Management API.

将来，IndexedDB可能会使用持久性类型(也不可能，也不是一个好主意).

In the future, IndexedDB could possibly used persistance type (not likely and not good idea too).
