I run the development of TypeDB, which doesnt use Cypher but works really well as a graph database. Certainly it, and other graph databases like neo4j, are used in production at scale. However, a lot of oss databases are open core on some level, it just depends on where they draw the line. We draw it at clustering/high availability for the time being, the rest is in the CE version.
Hi HN, I'm CTO at TypeDB. We shipped an agent mode in our web Studio that lets you describe what you want in plain English and get executable database queries back. The blog calls it "vibe querying," which is a little tongue-in-cheek, but the workflow is what you expect: ask a question, get TypeQL, run it, iterate.
TypeDB's data model has a strict schema, higher-level abstractions (role-based interfaces, subtyping & inheritance), and hypergraph structures (n-ary relations & relations in relations) built in. This combination enables better AI query generation.
It's like giving the LLM a strongly typed language instead of a loosely typed one. With a relational db, the model has to infer relationships from foreign keys and naming conventions. With graph databases, there's no enforced schema. In TypeDB, the schema says "friendship is a relation with two friends, each played by a person" — the LLM gets a constraint space to navigate rather than guess at. It still gets things wrong — the post shows a syntax error it had to recover from — but the error surface is smaller and more correctable.
Would love to hear your thoughts. Happy to answer anything about TypeDB as well!
Same question! As I understand it:
CO2 pulled out of the ocean is replenished by atmospheric CO2, because limestone in the ocean dissolves too slowly to make up for the imbalance and it more readily comes in from the air.
But if that's true, then the calcium will actually not be replenished quickly in the ocean (not sure what the significance of this is)!
If it were true that the calcium is dissolved fast enough to replenish, then there must also be CO2 released from underwater limestone? Which means extracting Ca and CO2 will not remove any atmospheric CO2 really.
Alternatively, we do end up extracting Ca from the ocean that is not replenished (there's probably so much we don't care) and rely on the atmospheric CO2 to correct ph balance of the ocean?
