Ask HN: What's the SQLite of graph databases?

31 points·jraines··11 comments

. . . if such a thing exists.

I'm looking for something easy to install, relatively easy to use, with good reliability, for experimentation.

ArangoDB in an hybrid db that can do graphs. Easy to install and use, quite reliable - we use it in production.

https://www.arangodb.com/ (just a happy user)

What about TinkerGraph: http://tinkerpop.apache.org/docs/3.1.0-incubating/#tinkergra...

It is "TinkerGraph is a single machine, in-memory (with optional persistence), non-transactional graph engine that provides both OLTP and OLAP functionality."

Definitely neo4j. If you're on a mac, it's just 'brew install neo4j' and boom you have the free community edition.

Depending on what OP was after, neo4j is hardly a single file, in-process database.

Well, that is not strictly true. You can use neo4j embedded within Java: http://neo4j.com/docs/stable/tutorials-java-embedded.html

You are correct. I was responding more to this:

> easy to install, relatively easy to use, with good reliability, for experimentation

To add on a requirement that poster didn't specify: I've been looking for an embedded single file, in process graph database. Does anyone have a suggestion?

Based on http://www.butleranalytics.com/20-free-and-open-source-graph..., apparently there are BITSY https://bitbucket.org/lambdazen/bitsy/wiki/FAQ.md, BLAZEGRAPH https://www.blazegraph.com/product/embedded/, and others

Do you specifically want a graph database?

Because if not, SpatiaLite's VirtualNetwork module may work for you. Otherwise, neo4j.

Maybe you can try to use a relational DBMS to model the graph data: https://news.ycombinator.com/item?id=10316872

If you're using Python and your graph fits in memory, networkx + any database for persistence.
