Why are today’s AI data architectures broken? Giannis Polyzos and Hugh Evans unpack what’s failing.

Giannis Polyzos joins Hugh Evans to challenge the idea of choosing technology based on popularity.

Tired of not knowing why your home lab containers are crashing? In this video, we’ll walk through how to set up a consolidated logging pipeline using Aiven for PostgreSQL (with TimescaleDB), Fluentd and Grafana — all running on my upgraded Mac Mini home lab. The key insight: never keep your troubleshooting tools on the same machine that's giving you problems!

In this episode, we sit down with Viktor Kessler, co-founder of Vakamo, major contributor to Lakekeeper, and organiser of Apache Iceberg Meetup Europe, to explore the evolving world of Apache Iceberg. From architectural deep dives to open-source governance, Viktor shares insights from building an Iceberg REST catalog in Rust, launching a company around open data governance and growing the European Iceberg community from Dublin to Vilnius.

In Episode 4 of Elephant in the Room, we tackle a question many teams struggle with: how do you protect sensitive customer data from your own developers while still running and improving your web application? Join Jay Miller (Aiven) and Tim Schilling of Djangonaut Space as they explore a real-world privacy challenge. Djangonaut Space’s application process requires collecting personal information from applicants, but reviewers and contributors should not have access to identifying details. The goal: enable fair review and active development without exposing sensitive data.

Giannis Polyzos sits down with Hugh Evans to discuss whether Paimon is really just Iceberg, only better.

Welcome to Elephant in the Room – presented by Aiven, the live series where we explore the real-world challenges developers face when working with PostgreSQL, the database that everyone depends on but few fully leverage. In Episode 2, Jay Miller, Staff Product Advocate at Aiven, is joined by Alexis Roberson, Senior Developer Educator and feature flag enthusiast, to break down how feature flags help teams ship faster, reduce risk and improve user experiences in PostgreSQL-backed applications.

Giannis Polyzos chats with Hugh Evans about whether batch data processing is truly “good enough".

Season 2 of Get Kafka-Nated kicks off with Giannis Polyzos, member of the Fluss PMC, for a deep dive into one of data infrastructure’s longest-running debates: streaming vs. batch, or both? What we’ll cover: Timestamps: Useful links.

Data catalogs are no longer just for compliance - they are the essential context layer for AI. While LLMs are powerful, they fail without the "tribal knowledge" found in metadata. This session explores how to transform your catalog from a static repository into an active nervous system for AI agents.

Some queries are hard to solve with "basic" RAG. When questions require multi-step reasoning, full-document understanding (not just chunks), or aggregating many results that match specific criteria, simple retrieve-and-generate pipelines break down, we need agentic RAG. But this added capability comes at a cost: as agents plan, search, read, and iterate, they quickly use up a lot of context, which both degrades answer quality and increases costs and latency.

In this episode, we sit down with Viktor Somogyi-Vass, a veteran of the Kafka ecosystem who recently joined Aiven after nearly a decade at Cloudera. Viktor shares his journey from becoming an Apache Kafka Committer to tackling the most complex challenges in modern cloud-native streaming. We dive deep into the architectural shift from traditional data centers to the cloud, exploring how Diskless Kafka (Disaggregated Storage) is slashing costs and why KIP-1134 is the next frontier for true multi-tenancy.

The speakers Nikita Varentsov, Director of Engineering at Inkitt and Johan Jern, Co-founder and CTO at Realm will discuss their experiences on building data infrastructure for rapidly scaling companies with open source technologies. The conversation is led by Amine Slimane, Head of Solution Architects at Aiven.

Viktor Kessler is both co-founder of Vakamo, a company specialising in governance for Iceberg, and a major contributor to Lakekeeper, an open-source Iceberg REST catalog. His contributions to the Iceberg aren’t limited to pull requests: Viktor is also the organiser of the Apache Iceberg Meetup Europe and hosted some fantastic events in 2025 that brought the Iceberg community together all over Europe from Dublin to Vilnius.
