DataStax believes multi-model databases are the future

Thor Olavsrud | April 13, 2016
DataStax is strengthening operational database support for multiple data models, from key value to tabular, JSON and graph, and has added DataStax Enterprise Graph to its offering.

Multi-model databases are the next evolution of NoSQL technologies, Van Ryswyk says. They support multiple data models against a single, integrated backend. DataStax says a multi-model database platform should:

  • Support more than one post relational data model (e.g., tabular, JSON, graph) at a logical layer for ease of development for application developers
  • Ensure all models are exposed via cohesive mechanisms, avoiding cognitive context switching for developers
  • Have a unified persistence layer that delivers geo-redundant, continuously available characteristics and a common framework for operational aspects such as security, provisioning, disaster recovery, etc.
  • Empower a variety of use cases across OLTP and OLAP workloads
  • Deliver best-in-case TCO efficiency for the long haul to enable wider adoption within centralized IT teams

DataStax Enterprise Graph

On Tuesday, DataStax added to its own multi-model capabilities with the announcement of DataStax Enterprise (DSE) Graph, a scaled-out graph database built for cloud applications that need to manage highly connected data.

Graph databases are a specialized form of NoSQL database intended to address relational data, but in a much more efficient and scale-out manner.

"Graph is an excellent method of evaluating, expressing and analyzing previously unrecognized relationships in data," Gartner's Heudecker and fellow analyst Mark Beyer wrote in their July 2015 report, Making Big Data Normal with Graph Analytics. "Instead of examining and analyzing data as a set of discrete and unrelated atomic elements, graph allows for the exploration of the frequency, strength and direction of relationships in data."

Last year, DataStax, a provider of database software for cloud applications, acquired Aurelius, the team behind open source graph database Titan. That team has spent the past year building a new set of software that extends beyond the basic capabilities of titan but maintains backward compatibility, allowing Titan and other users of TinkerPop supported graph databases to migrate easily.

Because it is built on DataStax's existing Cassandra foundation, Van Ryswyk says DSE Graph also inherits key Cassandra benefits, including constant uptime, read/write/active-everywhere functionality, linear scalability, predictable low-latency response times and operational maturity. DSE Graph also incorporates enterprise-class extensions found in DataStax Enterprise, including advanced security, built-in analytics, enterprise search, visual management monitoring and development tooling.

"We evaluated DataStax Enterprise Graph against traditional databases for some of our large banking customers and found that DSE Graph improves performance by an order of magnitude when working with data sets that include a large number of nodes and relationships — on use cases such as client data for financial services," Anil Gurnani, Banking and Capital Markets Solution at IT solutions provider Mphasis, said in a statement Tuesday.

DSE Graph includes:

    • DataStax Enterprise Server. It delivers advanced graph database functionality that includes an adaptive query optimizer, automatic graph data partitioning, a distributed query execution engine and graph-specific index structures.
    • DataStax OpsCenter. OpsCenter has been updated to provide full provisioning, management and monitoring for DSE Graph.
    • DataStax Studio. This new, web-based solution helps developers visualize graphs and write/execute graph queries.
    • DataStax Drivers. Drivers are available for all popular development languages and enhanced to support the Gremlin graph language in addition to CQL and DSE Analytics/Search APIs.

DSE Graph will be sold as an option to either a DSE Standard or DSE Max subscription. Van Ryswyk says it will be generally available in Q2.
