Moving database partitions from replica nodes

Abstract:

Replicated partitions of a database may be moved from one or more replica nodes to a different primary node. The replica nodes may maintain replicated partitions of one or more primary partitions of a primary node servicing access requests to the primary partitions. The replicated partitions may be copied to a different node in order to cause the processing of access requests directed to primary partitions to be serviced by the different node. Replicated partitions of a database may be moved from replica nodes to perform a split operation or a merger operation.
