android - 在房间数据库中保存数据的存储限制是多少？

Question

我有一个带有房间数据库的应用程序。我如何知道已达到数据存储的最大限制？如果应用程序超过该限制会发生什么。它会影响已经存储的数据还是只是停止添加新数据？

Answer 1

来自 docs

The Room persistence library provides an abstraction layer over SQLite

所以我假设房间的限制与 SQLite 相同.

来自 Limits In SQLite

Maximum Database Size

Every database consists of one or more "pages". Within a singledatabase, every page is the same size, but different database can havepage sizes that are powers of two between 512 and 65536, inclusive.The maximum size of a database file is 4294967294 pages. At themaximum page size of 65536 bytes, this translates into a maximumdatabase size of approximately 1.4e+14 bytes (281 terabytes, or 256tebibytes, or 281474 gigabytes or 256,000 gibibytes).

我怀疑您是否会达到此限制，但我相信您可以填满设备上的所有可用内存。

How would I know that the maximum limit of data storage is reached?

检查 this answer , 很详细

What happens if the app exceeds that limit

我真的认为这取决于您执行的操作，但是为了避免崩溃，您可以像链接的答案中那样事先检查内存来处理它。
