Viktor Kessler

Co-founder @ Vakamo

Viktor Kessler is the Co-Founder of Vakamo (founded December 2024), where he focuses on Apache Iceberg and Lakekeeper Catalog technologies. His technical expertise spans modern data infrastructure with a particular emphasis on open-source technologies and lakehouse architectures. Prior to founding Vakamo, Viktor built his technical expertise through roles at Dremio, MongoDB, ERGO Group. Viktor is actively involved in the data infrastructure community, particularly around Apache Iceberg implementations. His current focus appears to be on transforming data analytics from cost centers to profit centers through innovative data products and open technologies like Apache Iceberg and Lakekeeper Catalog.

Summary

In this in-depth technical webinar, Viktor Kessler—co-founder of Vakamo and former tech leader at MongoDB and Dremio—dissects the engineering principles that make Apache Iceberg a cornerstone of the modern lakehouse. Expect a hands-on look at Iceberg’s architecture, REST catalog, metadata optimizations, security model, and a live Lakekeeper demo, plus a glimpse into forthcoming OLake integrations.

Chapters & Topics

Welcome and Speaker Introduction

Host frames the session goals and introduces Viktor’s background in distributed data systems, setting the stage for a code-heavy, architecture-first discussion.

Iceberg Lakehouse Architecture Foundations

Breakdown of table formats, manifest lists, snapshots, and how Iceberg reconciles data-lake flexibility with data-warehouse performance guarantees.

REST Catalog Deep Dive

Examination of distributed metadata management, multi-engine interoperability, and how REST Catalog decouples compute from storage at scale.

Metadata Optimization Techniques

Strategies for pruning, partition evolution, and manifest compaction that yield dramatic query-latency reductions in production clusters.

Enterprise-Grade Governance & Security

Fine-grained access control patterns, audit logging, and compliance features that satisfy strict CISO and regulatory requirements.

Live Demo: Lakekeeper in Action

Real-world performance benchmarks and implementation patterns using Lakekeeper, highlighting best practices for ingestion, maintenance, and recovery.

Future Directions: OLake Write-Compute Layer

Preview of planned OLake integration as a high-throughput write layer, covering optimization strategies and roadmap milestones.

Audience Q&A and Closing Thoughts

Open floor for engineering questions on deployment, tuning, and migration; Viktor shares actionable takeaways and next steps.

Action Items

  • Distribute session recording, slide deck, and demo code snippets to all registrants.
  • Share benchmark scripts and configuration files used in the Lakekeeper demo.
  • Provide a follow-up resource list (docs, blogs, OSS repos) for deep diving into Iceberg and OLake.

Key Questions

  • What are the trade-offs between REST Catalog and Hive/Glue catalogs in large enterprises?
  • How do manifest compaction and snapshot expiration impact long-term storage costs?
  • What design considerations should teams weigh when introducing OLake as a write layer atop existing Iceberg tables?
