I've been working on a graph database in Rust this year actually! I'd love to hear anything you can talk about wrt the query planner and/or how you decided to do cardinality estimation. I decided to go with an EAV graph which makes CE pretty complex, and it's been an interesting challenge to balance quality and speed and expressiveness in the query language

Are you ACID? And does this version have multi-tenancy?

What kinds of graph shapes or query patterns do you feel are the worst case for object storage?

This seems like a great idea.
What reassurance can you offer devs that are hesitant to try a new data-store?

We've been having some issues with intermittent performance on multi hop queries.
What's your p99 like for multi hops?

congrats on the launch! site and docs look great.
can you host this yourself or do you need to use helix-cloud? the chat thing on the side seems to push me to helix-cloud but it looks like that starts at like $600/mo which is above my experimentation budget.
looking for a db for an agent memory application and i'd probably start with something that's just self-hosted / freeish. postgres is working ok but I want to start ingesting server and chat logs.

Currently #5 on gdb-engines.com - definitely worth a look.

Where's the source code for the database itself? Looks like the repo is just a client.
Congrats on the launch!

Congrats on the launch George!
Looking forward to looking into the generalised AI memory layer when it comes out.

does it support fts/vector on edges of the graph?

How does this compare vs. Turbopuffer?

congrats! how does this compare to turbopuffer, surreal or other multi-model ones built on object storage or not
