Abstract
Processing responsibility for a data set may be split according to separately stored partitions of the data set. A data set may be stored in different storage units that separately store different partitions of the data set. Mapping information may be maintained indicating the assignment of a node to process access requests to multiple partitions of a data set. A split event may be detected for the node, and one or more partitions assigned to the node may be reassigned to a different node. The storage units for the reassigned partitions may be made accessible to the different node. Then mapping information can be updated to indicate change in assignment from the original node to the different node so that the different node can begin processing access requests for the reassigned partitions.
