Datastore read policy setting in Go
问题
在Google App Engine中，我正在尝试使用Go设置Datastore的读取策略。
Python可以使用read_policy = db.EVENTUAL_CONSISTENCY来实现，但是似乎没有Go的等效方法。你可以看到Go文档中缺少了这一部分。
https://developers.google.com/appengine/docs/python/datastore/queries#Python_Data_consistency
https://developers.google.com/appengine/docs/go/datastore/queries#Go_Data_consistency
有人可以帮忙吗？
英文:
In Google App Engine I'm trying to set the Datastore read policy using Go.
Python has this ability using read_policy = db.EVENTUAL_CONSISTENCY but there seems to be no Go equivalent. You can see that this section is missing from the Go documentation.

Can anyone help?

是的，目前似乎没有办法为祖先查询指定“最终一致性”（其他类型的查询始终是强一致性或最终一致性）。
您可以在https://code.google.com/p/googleappengine/issues/entry?template=Feature%20request上创建一个新问题。
如果您创建了一个问题，请在这里发布ID，以便其他人可以给它加星。
英文:
Yeah, it seems there's currently no way to specify eventual consistency for ancestor queries (other kinds of queries are always either strong or eventually consistent).
You could create a new issue on https://code.google.com/p/googleappengine/issues/entry?template=Feature%20request
If you do create one, please post here the ID so that others can star it.
