Abstract

With SQL systems aging beyond a quarter of a century, a debate is raging on the architecture of the next generation data stores. There has been a flurry of novel data stores ranging from NoSQL to NewSQL, Cache Augmented SQL, document stores, graph databases and others. The past decade has witnessed the introduction of more than 40 systems by diverse participants including social networking sites, e.g., Cassandra by Facebook and Voldemort by LinkedIn. To enhance the availability of data, some systems sacrifice strict consistency (Atomicity, Consistency, Isolation, Durability) properties for weaker forms of consistency (Basically Available, Soft-state, Eventual Consistency). Others scale to a large number of nodes by abandoning the relational data model and the concept of transactions. This talk provides an overview of these systems and makes predictions about the next generation data stores on the horizon.
