Abstract
Disclosed in some examples is a method, the method including detecting that an RDMS is recovering from a failure; sending a request for a last committed transaction on a replication component to the replication component; receiving, from the replication component, the last committed transaction which identifies a transaction that was the last committed transaction at a replication component at a time of RDMS failure; determining that a transaction log on the RDMS includes a transaction that had not yet been replicated at the time of RDMS failure which was committed on the transaction log subsequent to the last committed transaction received from the replication component; and based on that determination rolling back the transaction that had not yet been replicated at the time of RDMS failure.
