The number of machines in a cluster of computers running a distributed database, such as a scalable hyperlink datastore or a distributed hyperlink database, may be changed such that machines may be added or removed. The data is not repartitioned all at once. Instead, only new and merged data stores are mapped to the changed set of machines. A database update mechanism may be leveraged to change the number of machines in a distributed database.
