>
> Currently replicas for the same region are spread across region servers.
> However, one region server may serve disproportionately high number of
> primary region replicas. This has been observed in production cluster.
> This issue adds PrimaryRegionCountSkewCostFunction which facilitates
> balancing primary region replicas evenly across region servers.
