Abstract: A method for performing distributed transactions of a cluster. The method includes, in response to a lock request including a first epoch from a first node, setting a local epoch to a maximum of the first epoch and the local epoch, sending a first lock including the local epoch to the first node, and in response to a conflicting lock request including a second epoch from a second node, setting the local epoch to a maximum of the second epoch and the local epoch, where the conflicting lock request is delayed until after the first lock is released. The method further includes, in response to a reintegration request including a third epoch from the first node, setting the local epoch to a maximum of the third epoch and the local epoch and performing a reintegration based on the reintegration request, where the reintegration is logged using the local epoch.
