      Description

      Investigate the possibility of being able to do manual rehashing:

      • Approach used Dynamo (and Cassandra)
      • If you're adding 100 nodes, using manual rehashing could reduce traffic and make it more predictable
      • Could be called via JMX
      • But removing 10 nodes could be problematic. Unless number of owners is 11 or higher, which will guarantee that at least a copy of data is around

          Regarding the removal of nodes, why don't we tell the system which nodes we intend to remove beforehand, so it can actually work out if there might be inconsistencies (e.g. insufficient numOwners).
