问题描述
类似于此问题，是IndexedDB保证是持久的? IE.如果设备内存不足，Safari不会回收磁盘空间.
Similar to this question, is IndexedDB guaranteed to be persistent ? ie. Safari will not reclaim disk space if the device is low on memory.
推荐答案
Safari have "No Eviction policy", meaning it will not automatically clean the IndexDB on low disk pressure, without user doing it manually.
IndexDB是快速发展的功能之一，您可以期望在没有公告的情况下随时有不同的驱逐策略.您应该始终使用后备选项进行构建.
IndexDB is one of the fast evolving feature and you can expect to have a different eviction policy any time with no announcement. You should always build with fall back options.
Chrome浏览器具有明确的永久存储选项，这将确保无需驱逐，只要用户批准永久存储即可，并且基于Safari在实施PWA功能后追随Chrome的往绩，我们可以期待Safari在同一时间做(尽管它花了很多年编写了非常糟糕的文档).
Chrome has explicit persistent storage option which will guarantee no eviction, on user approval for persistent storage and we can expect Safari to do the same sometime, based on their track record of following Chrome in implementing PWA features(though its taking years with super bad documentation).
