At a recovery manager associated with a cluster, a determination is made as to whether a replacement for a first node of the cluster can be elected by the other nodes of the cluster using a first election protocol. The recovery manager selects a second node of the cluster as a replacement for the first node, based on data item replication progress made at the node, and transmits an indication that the second node has been selected to one or more nodes of the cluster.

Data within a database partition that is being migrated may be made available for access. Data within a database partition may be selected for migration. Writes to the selected data may be prevented while the data is being migrated. Writes to other data, or read access any of the partition, may be allowed during the migration of the selected data. Rollback events may be detected for a database partition that is being migrated, halting the further selection of data for migration and deleting the successfully migrated data at the copy of the database partition being created.
