We have a production system based on Neo4J (and Elasticsearch). We have had some hard times with Neo4J (cluster issues, deadlocks) but their support helped us figure out those issues. Honestly, a graph database made discussions with the domain expains MUCH easier. And the schemalessness made evolutions much easier. Our technical team embraced the concept really quickly. And the domain experts have a clean mental model of the data that were otherwise split between very unfriendly technologies (XML databases, files, CSV). We wonder whether Elasticsearch could be removed from our architecture (because managing 2 databases is a mess). But we do not know yet if Neo4J can handle both the load and the variety of search use-cases.
