Abstract
A system includes one or more processors configured to redistribute one or more originator data subsets among a plurality of originator nodes and determine data redistribution information pertaining to redistribution of the one or more originator data subsets among the plurality of originator nodes. The system further includes a communication interface configured to send data redistribution information to a replica system. The data redistribution information is used by the replica system to redistribute one or more corresponding replica data subsets among a plurality of replica nodes.
