Deuteronomy: Transaction Support for Cloud Data

The Deuteronomy system supports efficient and scalable

ACID transactions in the cloud by decomposing functions

of a database storage engine kernel into: (a) a transactional

component (TC) that manages transactions and their

“logical” concurrency control and undo/redo recovery, but

knows nothing about physical data location and (b) 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. In this paper, we describe the architecture

of our TC, and the considerations that led to it. Preliminary

experiments using an adapted TPC-W workload show good

performance supporting ACID transactions for a wide range

of DC latencies.
