Linkurious v1.7: Improved performance with AllegroGraph and DataStax Enterprise Graph, SSL support for DSE

The new major release of our graph visualization software Linkurious Enterprise is now available! The release is named Zealous Zebra. Performances for Franz AllegroGraph (AllegroGraph) and DataStax Enterprise Graph (DSE Graph) have been significantly improved. In addition, Linkurious Enterprise now supports SSL communication with DSE Graph.

Linkurious Enterprise now supports SSL communication with DSE Graph to enable a secure communication channel between Linkurious Enterprise and DSE Graph. When configuring data sources, administrators simply need to use a secure WebSocket URL (wss://) for DSE Graph.

In this new version, we focused on improving the performances of Linkurious Enterprise with DSE Graph and AllegroGraph.

We benchmarked Linkurious Enterprise performances using the LDBC reference dataset (3.2 million nodes and 17.4 million of edges in DSE Graph, 47 million statements in AllegroGraph) using identical hardware and monitored the execution time of typical usage scenarios.

We improved our DSE Graph and AllegroGraph connectors and achieved between 50% and 95% faster queries, in particular in scenarios involving supernodes.

We updated the Linkurious Server to Node.js v7.5.0 which contains performances improvements and security fixes, including an upgrade to OpenSSL v1.0.2k.

• Usernames are no longer case sensitive
• Filters are now applied in widgets generated by the server
• DSE Graph raw query does not fail anymore when returning literal values
• Visualizations with an image palette can now be saved
• Paginate the expanded adjacent nodes with Neo4j
• AllegroGraph ID property is now optional in the server configuration.

In the next release, we will offer support to MSSQL and deliver a new process manager to allow Linkurious to be installed as a service on Microsoft Windows.
