我已将 Ensembles v2.5 集成到我的应用程序中,并且我正在使用 CloudKit 文件系统。如 Ensembles 文档中所述,通过推送通知自动触发合并。

通常同步有效,但我的问题是,在通过 CloudKit 将更改同步到第二台设备后,第二台设备似乎将新的事务日志上传到 CloudKit,这会在第一台设备上触发另一个合并(通过推送通知)。有时会在第二台设备上进行另一次合并,从而导致两次不必要的合并。

一个实际示例:
1) 设备 1 (iPad) 进行更改
2) 更改传播到 CloudKit
3) 推送通知触发器在设备 2 (iPod Touch) 上合并

iPad 和 iPod Touch 现在具有相同的数据,不应再发生合并,但是:

4) iPod Touch 创建新事务日志
5) 在 iPad 上合并推送通知触发器
6) iPad 创建新事务日志
7) 推送通知触发器合并 iPod Touch

这是设备 2 (iPod Touch) 上的 Ensembles 跟踪

在我看来奇怪的是,Ensembles 跟踪指的是 2 家商店:
- 一个 id 为 826D4BD2-2ED2-4C3B-9A89-22E3D910EC55-476-000000FAF9F774C3
- 一个 id 为 0B96EB62-03B1-414F-BBA5-3FCBDD2E9CD4-7677-0220002E

作为参考,这是我设置 Ensembles 的方式:

_ensemble = [[CDEPersistentStoreEnsemble alloc] initWithEnsembleIdentifier:DM_ENSEMBLE_IDENTIFIER
                                                        persistentStoreURL:storeURL
                                                     managedObjectModelURL:[self _getManagedObjectModelURL]
                                                           cloudFileSystem:_iCloudFileSystem];

非常感谢任何正确方向的帮助/指示。

这是预期的行为,最后一次合并应该非常快。如果您发现它太多,您可以轻松地选择限制由推送通知触发的合并。例如。如果在合并后的一分钟内出现推送,您可以选择忽略它。

每次更改的 3 次合并不是空操作。他们正在做重要的会计工作,以确保所有设备最终都获得相同的数据。

想想像 Git 这样的集成。在内部,基本上就是这样。现在,您在一台设备上进行更改,这会在该设备上触发新的提交 ( S1_D1)。然后进行合并以将数据推送到云端。

由于推送通知,第二个设备现在合并以获取该数据,并为此创建一个提交 ( M1_D2)。这可能包括也可能不包括冲突解决,但这对并发系统很重要。它在 Git 中相当于合并两个分支,你必须有一个新的提交来代表历史。

合并(M1_D2)被推送到云端,现在原始设备看到一个新的提交,并且必须执行合并操作来导入它,尽管它本身不会产生任何新的提交。

因此,单个保存应该需要在原始设备上进行合并,在其他设备上进行合并,然后在原始设备上进行另一次合并,才能完全完成。这就是它在像 Git 这样的系统中以及在 Ensembles 中的工作方式。

请注意,虽然需要 3 次合并操作,但您可以完全控制它们何时发生。您可以随意延迟它们,或者忽略我提到的某些推送。当你最终合并时,系统足够聪明,可以解决所有问题(就像 Git 一样)。
