Riak Automatically Re-Distributes Data When Capacity is Added

about 2 years ago

When you add (or remove) machines, data is rebalanced automatically with no downtime. New machines claim data until ownership is equally spread around the cluster, with the resulting cluster status updates shared to every node via a gossip protocol and used to route requests. This is what makes it possible for any node in the cluster to receive requests. The end result is that developers don’t need to deal with the underlying complexity of where data lives.
