[Gluster-devel] AFR write scheduling

I don't remember anything about the status of this, and I can't find it 
in the archives from a few minutes of searching, so I'll just ask.

Is afr write scheduling planned for the future?  My understanding of AFR 
currently is that if you have a 4 node AFR, and you specify all .html 
files to be redundant at 2 locations and all .db files to be redundant 
in 3, you can expect the first 2 defined nodes to contain redundant 
.html files and the first 3 nodes to contain redundant .db files and the 
fourth node to be essentially empty (until the other nodes fill up?).

Are there any plans to have it use a scheduler to decide which AFR nodes 
to write to?

Is the solution just to wrap multiple AFRs in a unify and use the unify 
scheduler to achieve this?
