Abstract
Embodiments are directed to providing database access during database reconfiguration and to maintaining replication connections during database reconfiguration. In an embodiment, a computer system establishes multiple quorum sets of replicas to replicate the data of a data partition. The quorum sets of replicas ensure that at least a minimum number of replicas are operating to commit pending transactions during partition reconfiguration. The computer system determines that a data partition reconfiguration has been initiated and provides access to the data partition's data during reconfiguration of the data partition using at least a quorum of replicas in each of the quorum sets of replicas.
