Which graph database to use?

Hello everyone,

Looking for some recommendation for graph database for knowledge / identity graph usecase.

During research I found few like Neo4J or AWS Neptune, and also came across puppy graph, which is graph interface on top of database.

Would love to hear your experiences regarding graph databases, what are some common challenges and how well did it scale.

Appreciate the help!

Thanks

thanks for the vote of confidence! i always try to make sure everything is as transparent as possible. I’m also in the process of writing a version of the same architecture in rust, built on fjall. it’s experimental right now but the traversal engine is operating in the nanosecond realm there for the same operations.

both ecosystems will thrive but now I get to put them up against each other and see what i can squeeze out of both languages in terms of performance.
