Redis does a lot of things most people don't know about and its all super optimised.. I am not so sure. I would not want that happen simple as I would be really bored using one way to do everything ( prb sql )

Most people use it as a cache,.. you can build a lot of things with it that are far outside this narrow view... ( say a bidding system or something like that )

And for the other comment Scaling is possible via the commercial offering.. sofaik..

I didn't get to persuade anyone to let me use it for that.. I really wanted to.
