Exploring the mechanisms of data versioning and time travel in an immutable file system, with a focus on transitioning between versions using multiple roots and pointers for atomic transactions, akin to Git repositories.

Apache Iceberg is an open source high-performance format for huge data tables. Iceberg enables the use of SQL tables for big data, while making it possible for engines like Spark and Hive to safely work with the same tables, at the same time.

Iceberg was started at Netflix by Ryan Blue and Dan Weeks, and was open-sourced and donated to the Apache Software Foundation in November 2018. It has now been adopted at many other companies including Airbnb, Apple, and Lyft.

Ryan Blue joins the podcast to describe the origins of Iceberg, how it works, the problems it solves, collaborating with Apple and others to open-source it, and more.
