Comparison OrientDB vs Titan and Neo4j?

• lvca 14y ago
  Neo4J is a pure GraphDB with a good level of maturity and support, but lacks on scalability in comparison to OrientDB (that offers a multi-master approach) and Titan (based on HBase/Cassandra). I think Titan (that is the most recent) is a good choice if you've many servers and huge parallel workload. Furthermore Neo4J has a dual license model and the high-available is pretty costly (http://www.neotechnology.com/price-list/ http://www.neotechnology.com/price-list/) while OrientDB and Titan are both released under the Apache License (=commercial friendly). About the model even though all these products supports the same interface (Blueprints) OrientDB is more flexible allowing sub-types for Edges and Vertices where to apply constraints. My 0,02. Lvc@

  Titan is to Neo4j, as Cassandra is to SQLite.

    Could you please explain? Am unfamiliar with Cassandra and Titan. :-)

      Here's last Friday's Titan 0.3 HN announcement that includes info on both: https://news.ycombinator.com/item?id=5462073 https://news.ycombinator.com/item?id=5462073

  Addition to what lvca (the author himself :) ) said, Unlike other pure GraphDB's, OrientDB is a hybrid DB, ie. under-the-hood its a document DB, so you will get best of both (if you want).
