alt Hacker NewsYay for Postgres! Curious if you find yourself using recursive queries in Postgres to traverse the graph - or is there an LLM in the mix that's looking at the "frontier" of relevant facts and choosing whether to go deeper, and whether an entity has an alias?
(Along those lines, I recall lots of this getting messy in a pre-LLM project the moment someone said "merge these two CRM accounts and their histories, but oh whoops turns out they were different all along, and only some of the updates should have applied" - there's a whole set of interesting challenges around attributing EAV when the very notion of object identity evolves over time. Whether a fact is relevant is really a judgment that can only be made with full context - but we now have tools that eat context for breakfast!)
very sharp questions, love 'em. Yes, your intuition is correct. We by default will gather information k layers removed from the "frontier", and then have a shallow agentic step that can determine if we need to go further and at what nodes (essentially doing a graph traversal without a fixed termination condition). Relevance detection is a hard problem; we think we have something good, and we're experimenting/iterating towards something great
