问题描述

是否有一些利弊来实现该功能?

Is there some pros or cons to not implement that feature?

我知道一些解决方案存在，并且已经在路线图上，但是这个决定背后有我们没有被授予的任何优势吗?

推荐答案

在有关Github的讨论中(请参阅

In a discussion on Github (see realm/realm-cocoa#2591) the Realm team said there are no plans for support any auto increment field, even if there's a few lines of code a developer can use for implementing this feature as you said.

在讨论中来自Realm成员:

From a Realm member in the discussion:

我们决定不支持此功能，因为通过多个进程同时访问将无法支持它.

We decided that we're not going to support this feature, because we would be unable to support it with simultaneous access from multiple processes.

就这样.
