At first I thought there is a chance that someone thought about the advantage of the same thing. I have always thought that cache products that lets you build your custom distributed data structure would be a marvellous thing and while Redis does not provide the same feature it sort of allow one to build much more complex cache data structure using its primitive. But given that its implemented as a single threaded async server I have to assume its Redis inspired.

Now the curious question is whether it provides some different feature, its a learning exercise or something else.
