Abstract
Disclosed are various embodiments for failover recovery in a distributed data store. A computing device determines whether it is a master data store in a distributed data store. New data item updates are assigned the next transaction identifier in a gapless numbering scheme relative to the most durably persisted entry. New data item updates are also associated with a data store identifier that identifies the new master data store.
