Distributed database transaction protocol

Abstract:

Technologies are described for facilitating transaction processing within a database environment having a coordinator node, a first worker node, and at least a second worker node. The coordinator node receives local transaction tokens from the first and the at least a second worker nodes. The coordinator nodes determines a synchronized transaction token using at least the local transaction tokens from the first and the at least a second worker nodes. The coordinator node sends the synchronized transaction token to the first and the at least a second worker nodes.
