Deuteronomy: Transaction Support for Cloud Data

Free registration required

Executive Summary

The Deuteronomy system supports efficient and scalable ACID transactions in the cloud by decomposing functions of a database storage engine kernel into: a Transactional Component (TC) that manages transactions and their "Logical" concurrency control and undo/redo recovery, but knows nothing about physical data location and a Data Component (DC) that maintains a data cache and uses access methods to support a record-oriented interface with atomic operations, but knows nothing about transactions. The Deuteronomy TC can be applied to data anywhere (in the cloud, local, etc.) with a variety of deployments for both the TC and DC.
