🌟 Apache Iceberg REST Catalog: What’s New and What’s Next
The Iceberg REST Catalog is quickly becoming the go-to way of connecting different engines and platforms to Apache Iceberg tables. But what does it actually solve, and where is the community taking it next? In this session, we’ll start with a quick intro to the REST Catalog and why it’s needed, before diving into hot topics like security, authentication, and fine-grained access control. We’ll also explore the latest developments in the community — including the new Events Endpoint — and talk about what’s coming down the road. If you’re curious about how Iceberg REST is shaping the future of open lakehouses, this is your chance to get up to speed and join the discussion.
Viktor Kessler, is Co-Founder of Vakamo and the creator of Lakekeeper, an Apache Licensed Iceberg REST Catalog. He’s a big believer in open standards like Apache Iceberg, which he sees as the backbone of today’s modern, composable Data & Analytics systems.
🌟 Iceberg + Trino/Starburst – latest enhancements including Iceberg v3 support and branching capabilities
This talk provides a concise overview of connecting Trino directly to Iceberg, setting the stage for a demonstration of the latest integration enhancements. We will showcase new features from Iceberg v3, including deletion vectors, the variant type, and data lineage. If time allows, we will also explore Iceberg data branching with Trino and Starburst.
Grzegorz Kokosinski is Engineering leader at Starburst helping teams build and operate Trino at scale. I guide architecture, mentor engineers, and balance performance, reliability, and simplicity—preferring steady, transparent progress over hype.
🌟 Standardized Lineage for Apache Iceberg Tables With OpenLineage
Apache Iceberg has become the de-facto open table format for building data lakes and lakehouses.
But as organizations adopt Iceberg across multiple compute engines - Spark, Flink, Trino, Snowflake, BigQuery, and more,
data teams struggle to maintain a unified view of lineage and metadata across these distributed systems.
In this talk, we explore how OpenLineage provides a vendor-neutral standard for lineage,
and how it can be combined with Iceberg's rich metadata model to build a complete cross-platform lineage graph.
We will discuss how lineage events can be captured from diverse engines,
how Iceberg metadata can be used to enhance operational lineage, and how the data can be
used to provide a complete health view of your data platform.
Maciej is a Senior Software Engineer at Datadog, Apache Airflow and OpenLineage committer. In the free time he likes petting his cat, rock climbing and contributing to Open Source projects.
🌟 Building multi-engine workloads on Iceberg & Bruin
In this talk, Burak Karakan (Co-founder & CEO of Bruin) walks through how to design and operate multi-engine workloads on Apache Iceberg. He’ll cover practical patterns teams use to combine DuckDB, Redshift, Trino, and Bruin’s MCP integration to build fast, reliable, and unified lakehouse pipelines.
Burak Karakan is the Co-founder & CEO of Bruin, the open-source, AI-native data engineering platform behind ingestr and Bruin CLI. Before Bruin, he spent five years at HelloFresh leading teams building large-scale systems. He now focuses on unifying ingestion, transformation, quality, and AI agent workflows into a single modern data toolkit.
🌟 Fluss as the hot layer for your Iceberg Lakehouse
Fluss is columnar stream storage built for analytics, a new technology designed for real-time data pipelines recently donated to Apache Software Foundation.
In version 0.8 (released last month) the Iceberg integration was added.
In this session I'll explain:
- what problems Fluss is solving
- what features are already there
- how it can be used to build real-time data pipelines natively on Iceberg
Jan is Data Streaming Consultant with deep background building event-driven microservices in Java and Kotlin.
Content creator and speaker publishing actively about Data Streaming on LinkedIn and YouTube.
Apache Fluss enthusiast.
