MongoDB + Neo4J vs OrientDB vs ArangoDB [closed]

Disclaimer: I am the author and owner of OrientDB.

As developer, in general, I don't like companies that hide costs and let you play with their technology for a while and as soon as you're tight with it, start asking for money. Actually once you invested months to develop your application that use a non standard language or API you're screwed up: pay or migrate the application with huge costs.

You know, OrientDB is FREE for any usage, even commercial. Furthermore OrientDB supports standards like SQL (with extensions) and the main Java API is the TinkerPop Blueprints, the "JDBC" standard for Graph Databases. Furthermore OrientDB supports also Gremlin.

The OrientDB project is growing every day with new contributors and users. The Community Group (Free channel to ask support) is the most active community in GraphDB market.

If you have doubts with the GraphDB to use, my suggestion is to get what is closer to your needs, but then use standards as more as you can. In this way an eventual switch would have a low impact.

It sounds as if your use case is exactly what ArangoDB is designed for: you seem to need different data models (documents and graphs) in the same application and might even want to mix them in a single query. This is where a multi-model database as ArangoDB shines.

If MongoDB has served you well so far, then you will immediately feel comfortable with ArangoDB, since it is very similar in look and feel. Additionally, you can model graphs by storing your vertices in one (or multiple) collections, and your edges in one or more so-called "edge-collections". This means that individual edges are simply documents in their own right and can hold arbitrary JSON data. The database then offers traversals, customizable with JavaScript to match any needs you might have.

For your variations of the queries, you could for example add attributes about these embargos to your vertices and program the queries/traversals to take these into account.

The ArangoDB database is licensed under the Apache 2 license, and community as well as professional support is readily available.

Neo4j's pricing is actually quite flexible, so don't be put away by the prices on the website. You can also get started with the community edition or personal edition for a long time.

The Neo4j community is very active and helpful and quickly provide support and help for your questions. I think that's the biggest plus besides performance and convenience. In general using a graph model

Regarding your use-case:

Neo4j is used exactly for this route calculation scenario by one of the largest logistic companies in the world where it routes up to 4000 packages per second across the country.

And it is used in other game engines, like here at GameSys for game economy simulation and in another one for the routing (not in earth coordinates but in game-world-coordinates using Neo4j-Spatial).

I'm curious why you have only that few nodes? Are those like transport portals? I wonder where you store the details and the dynamics about the routes (like the criteria you mentioned) are they coming from the outside - in memory state of the game engine?

You should probably share some more details about your model and the concrete use-case.

And it might help to know that both Emil, one of the founders of Neo4j and I are old time players of multi user dungeons (MUDs), so it is definitely a use-case close to our heart :)
