Deuteronomy: Transaction Support for Cloud Data
The Deuteronomy system supports efficient and scalable ACID transactions
in the cloud by decomposing the storage engine into: (a) a transactional
component (TC) that manages transactions and their “logical”
concurrency control and undo/redo recovery, and (b) a data component
(DC) that knows about the access methods and supports 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 components. In
this talk, we first describe the architecture of our TC, and the
considerations that led to it. We next describe the contract between TC
and DC, how we changed the operation protocol to simplify it and make it
more efficient. We have implemented both TC and multiple DCs, and will
describe our TC implementation in detail. We will end a few words about
observed performance and scalability.
