Jean-Daniel Cryans updated KUDU-1728:
-------------------------------------
    Target Version/s: Backlog

>From recent experience, I think this would be great. If we could define a 
>tserver-wide IO budget and on-the-fly decide if a tablet copy can do more (or 
>less) in parallel then this could resolve some re-replication situations 
>faster.

Another similar idea, maybe instead of doing many tablets in parallel we should 
instead focus on re-replicating single tablets as fast as we can? It might 
become more difficult to get good parallelism over a cluster though since 
there's fewer copy operations going on.

> Parallelize tablet copy operations. Right now all data is copied serially. We 
> may want to consider throttling on either side if we want to budget IO.
