Abstract
Data replication is disclosed. Originator data subsets are redistributed among a plurality of originator nodes from an initial distribution arrangement to a new distribution arrangement. Data redistribution information is determined. The redistribution information includes identification information of the originator data subsets, identification information of originator nodes comprising the initial distribution arrangement, and identification information of originator nodes comprising the new distribution arrangement. The redistribution information is sent to a replica system comprising a plurality of replica nodes. The redistribution information is used by the replica system to redistribute corresponding replica data subsets among a plurality of replica nodes from a previously replicated arrangement to a new replicated arrangement.
