Ontotext Improves Its RDF Triplestore, GraphDB™ 6.0

ontotextSofia, Bulgaria (PRWEB) August 20, 2014 - GraphDB™ 6.0 from Ontotext was released today including improvements to the enterprise replication cluster, faster loading speeds, higher update rates and connectors for Lucene, SOLR and Elasticsearch. This release happens to coincide with a name change for this high performance triplestore – GraphDB™ was formerly known as OWLIM. Now, organizations interested in deploying the only mature enterprise resilient RDF triplestore will also benefit from advanced search functionality using the best full-text search engines without additional integration and synchronization efforts.

“Customers like BBC have had great success with our high availability enterprise replication cluster” reports Atanas Kiryakov, Executive Director and Founder of Ontotext. “Because of this, we improved the cluster architecture to guarantee even higher fault tolerance, faster recovery mechanisms and reliable synchronization across geographically remote data centers. In addition, we improved loading speeds by 3 to 5 times. Tests against 10’s of billions of triples indicate approximately 300,000 RDF statements loaded per second on a single commodity database server.”

GraphDB™ Connectors allow for integration with search engines and NoSQL databases. Currently, connectors for SOLR, Lucene and Elasticsearch are supported. Ontotext reports they are testing others as well. The SOLR connector has already been deployed allowing SOLR queries to be embedded as part of SPARQL queries. The connector takes care of synchronization allowing for updates in the RDF database to instantly trigger updates of the SOLR indices. When transactions in GraphDB™ are committed and complete, SOLR's indices are already updated and ready to be used.
