Office Hours: Branching and Tagging Apache Iceberg Tables

Most teams using Iceberg in production are only scratching the surface of what it can do. Snapshots and time travel are table stakes—branching, tagging, and rollback workflows are where Iceberg starts to feel like a proper engineering discipline rather than just a file format. In this 30-minute office hours session, Starburst expert Lester Martin will walk through how to use Iceberg’s branching and tagging capabilities to make your lakehouse safer to operate, easier to recover, and more controlled to deploy.

In this session, we’ll cover:

• Branching and tagging differences, including basic snapshots and when to use each
• Blue-green–style data deployments using Iceberg branches
• Rollback patterns for incident recovery in production lakehouses
• Workflows for multi-tenant environments where safe experimentation matters

Bring your Iceberg questions. There will be plenty of time for Q&A. Have something you’d like to see in action? Ask Lester when you join, and he can walk you through your specific problem live.
