Abstract

Various examples are directed to systems and methods for operating a primary database management system and a secondary database management system. The secondary database management system may receive a takeover request indicating that the secondary database management system is to assume a role of the primary database system. The secondary database management system may determine that a last valid commit of a first host of the secondary database system is an oldest last valid commit. The secondary database management system may revert to a first state of the primary database management system corresponding to the last valid commit of the first host. The secondary database management system may be configured to assume the role of the primary database management system.
