It's interesting to think of where the value comes from. Afaict 2 interesting areas: A: One of the main lessons of the RAG era of LLMs was reranked multiretrieval is a great balance of test time, test compute, and quality at the expense of maintaining a few costly index types. Graph ended up a nice little lift when put alongside text, vector, and relational indexing by solving some n-hop use cases. I'm unsure if the…

I'm conceptually very bullish on B (entity resolution and hierarchy pre-processing during writes). I'm less certain than A and B need to be merged into a single library. Obviously, a search agent should know the properties of the KG being searched, but as the previous poster mentioned, these graph dbs are inherently inaccurate and only form part of the retrieval pattern anyway.

Cypher-over-Gremlin is a smart call — LLMs can write Cypher, makes the MCP angle viable in a new way. How dos Yjs handle schema migrations? If I add a property to a vertex type that existing peers have cached, does it conflict or drop the unknown field?

Can anyone explain why it is a good idea to make a graphdb in typescript? This not a language flamewar question, more of an implementation details question. Though typescript is pretty fast, and the language is flexible, we all know how demanding graph databases are. How hard they are to shard, etc. It seems like this could be a performance trap. Are there successful rbdms or nosql databases out there written in type…

I needed it to be possible to run the graph in the browser and cloudflare workers, so TS was a natural fit here. It was built as an experiment into end to end type safety - nothing to do with LLMs, but it ended up being useful in the product I'm building. It's not designed for large data sets.

I'm not terribly familiar with graph databases, but perhaps someone who is can explain the advantage of this awfully complicated seeming design. There's gremlin, cypher, yjs, and zod, all of which I understand are different languages for different problems. What's the advantage of using all these different things in one system? You can do all of this in datalog. You get strong eventual consistency naturally. LLMs kno…
