Does Future work on App Engine?

Does the Future library works on App开发者_运维知识库 Engine? If not, what is a good alternative library that does work on top of GAE?

You cannot use threading on App Engine. See Are there any third-party libraries not supported by Google App Engine?, which includes the bullet point "Threading is not available".

You might be able to accomplish what you need to accomplish via the Task Queue api. See Python Threads (or their equivalent) on Google App Engine for (slightly) more info.
