The LARUS company has been a Neo4j partner since 2015, providing consultancy and training services. They have worked with various companies in Italy, including Cerved, which uses Neo4j to store its business network. The Couchbase connector is an example of the tool's effectiveness, featuring bi-directional relationships and configurable connectors. The architecture of the connector consists of four main components: a Couchbase listener, a JSON loader, a Neo4j mutation listener, and a Couchbase JSON loader. These components work together to transform JSON data into a graph database. The domain-driven transformer allows for reusing "U2" and other nodes, enabling relationships to be built on top of the data. LARUS also contributed to the development of community drivers for Neo4j 3.0, including a standard JDBC interface and a Bolt protocol implementation.
