Infinite, shareable volume storage with Hunter Leath, Archil CEO
Hunter Leath, CEO of Archil, explains how they’re building a “universal storage engine” that sits between your apps and S3—making an S3 bucket behave like a fast, POSIX-compatible disk for containers, servers, and even Lambda. Along the way, we dig into how their SSD-backed clusters and custom protocol avoid the usual small-file pain and where this approach shines (and where it doesn’t).

Building search for AI systems with Chroma CTO Hammad Bashir
Hammad Bashir, CTO of Chroma, joins the show to break down how modern vector search systems are actually built from local, embedded databases to massively distributed, object-storage-backed architectures. We dig into Chroma’s shared local-to-cloud API, log-structured storage on object stores, hybrid search, and why retrieval-augmented generation (RAG) isn’t going anywhere.

Scaling DuckDB in the cloud with MotherDuck CEO Jordan Tigani
In this episode of Database School, Aaron Francis sits down with Jordan Tigani, co-founder and CEO of MotherDuck, to break down what DuckDB is, how MotherDuck hosts it in the cloud, and why analytics workloads are shifting toward embedded databases. They dig into Duck Lake, pricing models, scaling strategies, and what it really takes to build a modern cloud data warehouse.

Infinite, shareable volume storage with Hunter Leath, Archil CEO
Published 15 Jan 2026 · Transcript excerpt
[…] Yeah, and I think that sequel light is a really good example because there are so many applications that have been written over the past 50 years. And the vast majority of those applications still require that you have a file system to run them on. And when you log in to SSH, you're expecting to touch files and MV files and RM files, which just aren't things that translate so well to S3 as it exists today. And so we see this usability gap as this piece that we can solve. But when we talk about providing this ability to transform S3 into a format that's understandable to Linux and sequel light, I think a lot of people have reservations because they've used existing you know fuse tools like S3FS or goofyFS that like either compromise on performance or compromise on correctness that make them feel like they can't use this for anything real. […]
