The Neo4j team has overhauled their Sandbox infrastructure, upgrading it to run on self-contained Docker images on AWS Fargate managed by a Lambda-Function-based API for easier scaling. The new Sandboxes now feature Neo4j 4.2 (Enterprise) with major updates including multi-database support, fine-grained permissions, and reactive drivers. The sandbox also comes with the latest versions of the APOC utility library, Graph Data Science Library, and Neosemantics RDF and linked data library. These features are used in their free online training classes, such as GraphAcademy. Users can now easily add their Sandbox as a Remote Database Connection to Neo4j Desktop and invite collaborators to share their Sandbox. The code examples have been updated with interesting queries for each dataset, and the datasets themselves are available on GitHub. The content of user Sandboxes will be available as dump-files that can be imported into Neo4j Aura (Cloud) and Neo4j Desktop. The team invites users to provide feedback through various channels.
