azure - 在 OnOpenAsync 方法中调用 GetOrAddAsync

Question

我使用StatefulService与 IReliableDictionary .

目前，我调用StateManager.GetOrAddAsync<IReliableDictionary>我到处都需要这本词典。

最好的做法是只调用一次 StateManager.GetOrAddAsync<IReliableDictionary>在 OnOpenAsync方法StatefulService并将返回值存储在成员中？

这并不重要。 I've asked it给产品团队得到了这样的回复:

You can cache the result of GetOrAddAsync locally but it doesn't matter since the statemanager does that for you automatically. Some folks think it's easier to keep a local, but I never do because now you have some lifecycle things to deal with (you have a ref to the thing not protected by state manger acquisition locks so you can see some different exceptions, but nothing you wouldn't have to deal with anyway).
