Abstract:
Technologies are described for facilitating database system recovery in a distributed database environment having a master node and at least one slave node. The at least one slave node receives a preliminary slave log backup position. The at least one slave node replays at least a portion of one or more log backups until the preliminary log backup position is reached. The at least one slave node receives a final slave log backup position. The slave node replays at least a portion of one or more log backups until the final slave log backup position is reached.
