Apache Iceberg: the complete guide

Guides
Karel Sague·September 6, 2026·2 min read

Apache Iceberg is an open table format built to bring reliable, SQL-like tables to huge analytic datasets stored in an object store like S3, with ACID transactions, schema evolution, hidden partitioning, and time travel built in.

This hub is the entry point to what we have written about running Iceberg in production. It is new and will grow section by section as we publish more, starting with Iceberg use cases: real deployments, with the architecture and the numbers behind them.
