Abstract
We propose a consistency model for a data store in
the Cloud and work towards the goal of deploying Database as a Service over the Cloud. This includes consistency across the
data partitions and consistency of any replicas that exist across different nodes in the system. We target applications which
need stronger consistency guarantees than the applications
currently supported by the data stores on the Cloud. We
propose a cost-effective algorithm that ensures distributed
consistency of data without really compromising on availability
for fully replicated data. This paper describes a design in
progress, presents the consistency and recovery algorithms for relational data, highlights the guarantees provided by the system and presents future research challenges. We believe
that the current notions of consistency for databases might not
be applicable over the Cloud and a new formulation of the consistency concept may be needed keeping in mind the
application classes we aim to support.
