Michael Mior commented on CALCITE-1389:

Sounds like a great idea. I will admit that I don't have a great handle on some 
of the aspects you mentioned, but I think all of those should be included in 
the documentation. I think this is worth opening up a separate issue for which 
I'll do if there are no objections. Maybe we can get some stable documentation 
on existing use of MVs before pushing this further.

>  I've been looking into implementing the approach from the following paper. 
> It's very nicely written and easy to follow. It also doesn't require trying 
> different join permutations. I'm starting with several additional 
> restrictions (only equijoins, no aggregations, etc.)
