This release has several major changes to data placement in Swift in order to better handle different deployment patterns. First, with an unbalance-able ring, less partitions will move if the movement doesn¡¯t result in any better dispersion across failure domains. Also, empty (partition weight of zero) devices will no longer keep partitions after rebalancing when there is an unbalance-able ring.

Second, the notion of ¡°overload¡± has been added to Swfit¡¯s rings. This allows devices to take some extra partitions (more than would normally be allowed by the device weight) so that smaller and unbalanced clusters will have less data movement between servers, zones, or regions if there is a failure in the cluster.

Finally, rings have a new metric called ¡°dispersion¡±. This is the percentage of partitions in the ring that have too many replicas in a cluster but two replicas for a partition get placed onto the same server, that partition will count towards the dispersion metric. A lower value is better, and the value can be used to find the proper value for ¡°overload¡±.
