Status of project?

[joshcho]

I have taken a keen interest in this project; I have a small project and have both a vivace-graph version and a neo4j version, with significant speedup with vivace-graph version, so much so that I 'm willing to work with a largely unmaintained project. What are the authors' plan with this project? I am curious.

Hi Josh. I am currently volunteering in Ukraine and rarely have power or internet, much less time to code. Once this war is over, I will get back to maintaining VG. I am happy to support you as much as I can in the meantime, given my current situation.

[joshcho]

Thank you very much. Best of luck, I will submit pull requests in the meantime that may be helpful.

I am building something that requires a graph for each user. Would you recommend (in terms of speed and otherwise) having a user's graph be a subgraph of one large graph, or having a graph for each user? I haven't been able to get the latter to work.

Also, I noticed each graph is more than 2GB, which might hinder the multi-graph approach (though isolation would be really nice).

[kraison]

Multiple graphs is not an intended use case. It might work, but linking nodes between graphs definitely won't work as I suspect you intend.

Because this is a Lisp-based project, there are certain lines of demarcation that we are used to using that just don't fit. The best way to understand VG is not as a database separate from your code, but rather as a file-backed Lisp heap with user-defined indexing of objects. I highly recommend this book as one reference: https://en.m.wikipedia.org/wiki/The_Art_of_the_Metaobject_Protocol

[joshcho]

I have that book open on one of my tabs, this gives me more motivation to read it. Thanks!

How do you estimate the performance would look like if you have, say ~100M nodes and ~100M edges?

@kraison @joshcho Maybe until your return, there can be a maintained fork ? @joshcho did some good work, so maybe that's a good start.

[joshcho]

I made one or two changes, so I don't think they are good enough. Also unfortunately, I have moved onto other projects, so won't be of much help here.

Best of luck!
