> Per our discussion at the hackathon today, it seems that it would be more
> helpful to add a sloppiness check before doing the normal balancing.
> The current situation is that the balancer always tries to get the region
> load even, meaning that there can be some very frequent regions movement.
> Setting the balancer to run less often (like every 4 hours) isn't much better
> since the load could get out of whack easily.
> This is why running the normal balancer frequently, but first checking for
> some sloppiness in the region load across the RS, seems like a more viable
> option.
