Introducing Omnigraph – an open source, schema-first, lakehouse-native context graph engine built on Rust, Lance, Apache Arrow and DataFusion. It is S3-native infrastructure built to solve the problem of agent coordination.Omnigraph caught my attention so I brought the two authors to the podcast – Andrew Altshuler and Ragnor Comerford. It was a very densely-packed conversation where we covered everything around modern day AI engineering, including:- why a schema-first is a must for agents- the importance of guardrails in autonomous workloads (schemas, tests, linters, policies, and type systems)- what Omnigraph is, and how its being built/dogfooded at Modern Relay / how Slack + Linear start to break down with many parallel agents- how Lance, DataFusion, Arrow, and object storage fit perfectly into the open AI data stack- why proper agent coordination looks more like decentralized decision making than central planning- the importance of good taste (when agents can implement almost anything)- why AI massively compresses business timelines- and a lot more0:00 Why build a graph database for agents?5:43 Why not Postgres?
