A Newer, Faster and Better GraphDB in the Cloud

We are excited to share various updates and news related to the Cloud version of our RDF graph database, GraphDB™!

The latest GraphDB 6.4.2 is already available via the AWS Marketplace.64-onAWS


As of September 7th, customers can enjoy the latest and improved GraphDB database, instantly available on the AWS cloud, without the need for hardware and license provisioning. As always, GraphDB is available on a pay-per-use basis, where developers pay-per-hour of database usage. There are no one-time charges or subscriptions, and developers can stop the database at any time.
The latest version 6.4.2 includes several important improvements, such as:

  • Explain plan improvements
  • SPARQL 1.1 VALUES implementation
  • Storage tool with ability to repair indices or export index data into text files
  • Performance improvements
  • Improved handling of SPARQL queries with very large ResultSets
  • Various bug fixes and improvements

The self-managed database documentation contains details on configuring the GraphDB database on the AWS cloud.

5 Day free trial available for GraphDB on AWS

Developers can now use GraphDB on AWS for 5 days without any hourly charges. This ensures that developers will be able to setup and configure GraphDB in the Cloud and import data, before they start paying for actual usage.

Instance migration instructions are now available

The “Upgrading the GraphDB Product” section of the Self-managed database documentation now includes details on how developers can upgrade from one version of the product on the AWS Marketplace, to a newer one, so that all data and configuration settings are properly preserved.

LaunchonEC2 In summary, the migration process includes these simple steps:

  • starting a new EC2 instance with the latest version of the GraphDB product via the AWS Marketplace
  • stopping the GraphDB service/process on the old instance
  • detaching the EBS data volume from the old instance
  • re-attaching the EBS data volume to the new instance
  • starting the GraphDB service/process on the new instance
  • terminating the old instance which is no longer needed

Improved GraphDB Workbench

Versions 6.4.x of GraphDB include a completely redesigned and improved GraphDB Workbench – the web based tool for managing GraphDB databases.



As a reminder, your GraphDB Workbench will be up and running at http://:8080/graphdb on the EC2 instance where you deploy GraphDB.

Experimental Blueprints and Gremlin support

GraphDB 6.4.x now includes experimental support for the Blueprints API and the Gremlin graph query language.
Configuration instructions are available in the GraphDB documentation.

GraphDB Fundamentals videos

GraphDB Fundamentals is series of nine YouTube videos that will accompany developers new to Semantic Technology, with their first steps of using an RDF graph database. The video series cover topics such as:

    • the fundamentals of W3C standards for graph databases: RDF/S, SPARQL and Ontologies
    • GraphDB installation and performance tuning instructions
    • understanding GraphDB reasoning strategies and graph analytics extensions such as RDFRank, Geo-spatial and Full-Text-Search
    • troubleshooting of most common problems

Of course the GraphDB running on the AWS cloud has its own specifics: the installation is taken care of (you just deploy a pre-bundled AMI) and the configuration has to take care of some AWS specifics such as EC2 instances and EBS volumes. All these details are covered in the self-managed database documentation.

Ongoing upgrade of the fully-managed GraphDB database-as-a-service (DBaaS)

In addition to the self-managed GraphDB database in the Cloud, where users are in control of deploying, configuring and managing the graph database, our Self-Service Semantic Suite (S4) platform also provides a fully-managed database-as-a-service (DBaaS) where all details related to provisioning, upgrades, configuration and operations are taken care of on behalf of the users. The fully-managed database is running in the Cloud 24/7 and accessible via simple RESTful APIs.

DatabaseDetails We have started the migration of the DBaaS to the latest GraphDB 6.4.2 and soon S4 users will be able to enjoy a faster and improved RDF graph database.

Final words

If you haven’t already done so, register for a free developer account for the Self-Service Semantic Suite (S4), take a look at the developer’s documentation, configure your own RDF graph database in the Cloud and start building smart data prototypes with RDF and SPARQL!
