Returning transactions to distributed data stores

Principles for the next generation of NoSQL databases

By David Rosenthal and Stephen Pimentel

Rise of NoSQL

Database technologies are undergoing rapid evolution, with new approaches being actively explored after decades of relative stability. As late as 2008, the term “NoSQL”  barely existed and relational databases were both commercially dominant and entrenched in the developer community. Since then NoSQL systems have rapidly gained prominence and early systems such as Google’s Bigtable and Amazon’s Dynamo have inspired dozens of new databases (HBase, Cassandra, Voldemort, MongoDB, etc.) that fall under the NoSQL umbrella.

The first generation of NoSQL databases aimed to achieve the dual goals of fault tolerance and horizontal scalability on clusters of commodity hardware There are now a variety of NoSQL systems available that, at their best, achieve these goals. Unfortunately, the cost for these benefits is high: limited data model flexibility and extensibility, and weak guarantees for applications due to the lack of multi-statement (global) transactions.
