Mateusz Gienieczko | AnyBlox: A Framework for Self-Decoding Datasets | #69
In this episode of Disseminate: The Computer Science Research Podcast, host Dr. Jack Waudby is joined by Mateusz Gienieczko, PhD researcher at TU Munich and co-author of the VLDB Best Paper Award winning paper AnyBlox.
They dive deep into a fundamental problem in modern data systems: why cutting-edge data encodings and file formats rarely make it from research into real-world systems — and how AnyBlox proposes a radical solution.
Mateusz explains the core idea of self-decoding data, where datasets ship with their own portable, sandboxed decoders, allowing any database system to read any encoding safely and efficiently. Built on WebAssembly, AnyBlox bridges the long-standing gap between database research and practice without sacrificing performance, portability, or security.
This episode is essential listening for database researchers, data engineers, system builders, and industry practitioners interested in the future of data formats, analytics performance, and making research matter in practice

Xiangyao Yu | Disaggregation: A New Architecture for Cloud Databases | #68
In this episode of Disseminate: The Computer Science Research Podcast, host Jack Waudby sits down with Xiangyao Yu (UW–Madison), one of the leading voices shaping the next generation of cloud-native databases.
We dive deep into disaggregation — the architectural shift transforming how modern data systems are built. Xiangyao breaks down:
Why traditional shared-nothing databases struggle in cloud environments
How separating compute and storage unlocks elasticity, scalability, and cost efficiency
The evolution of disaggregated systems, from Aurora and Snowflake through to advanced pushdown processing and new modular services
His team's research on reinventing core protocols like 2-phase commit for cloud-native environments
Real-time analytics, HTAP challenges, and the Hermes architecture
Where disaggregation goes next — indexing, query optimizers, materialized views, multi-cloud architectures, and more
Whether you're a database engineer, researcher, or a practitioner building scalable cloud systems, this episode gives a clear, accessible look into the architecture that’s rapidly becoming the default for modern data platforms.

Navid Eslami | Diva: Dynamic Range Filter for Var-Length Keys and Queries | #67
In this episode of Disseminate: The Computer Science Research Podcast, Jack sits down with Navid Eslami, PhD researcher at the University of Toronto, to discuss his award-winning paper “DIVA: Dynamic Range Filter for Variable Length Keys and Queries”, which earned Best Research Paper at VLDB.
Navid breaks down how range filters extend the power of traditional filters for modern databases and storage systems, enabling faster queries, better scalability, and theoretical guarantees. We dive into:
How DIVA overcomes the limitations of existing range filters
What makes it the “holy grail” of filtering for dynamic data
Real-world integration in WiredTiger (the MongoDB storage engine)
Future challenges in data distribution smoothing and hybrid filtering
Whether you're a database engineer, systems researcher, or student exploring data structures, this episode reveals how cutting-edge research can transform how we query, filter, and scale modern data systems.

Published 5 Mar 2026 · Transcript excerpt
[…] Yes. So there is a question about what do you want from this abstraction? Like what how do we evaluate? Right? Because I'm kind of learning how to have to properly do do research, but the way you're supposed to do science is like, okay, like how do we even test that we got what we wanted? And so the properties we described as first of all, portability, this is like the whole thing, right? Like we want to be able to use the same solution across all the different systems and the cost of integrating it shouldn't be too big. Because first of all, if we just allow you to do it only in some architectures or only with some kinds of systems, no one's going to use it. […]
