Part 3/10:

Introducing Data Lakehouses and Open Table Formats

The session emphasizes the advent of data lakehouses—architectures that combine the scalability of data lakes with the management and performance features of data warehouses. Central to this model are open table formats, which organize large datasets efficiently across distributed systems.

Among these, Apache Iceberg stands out as a leading open table format. Introduced by industry pioneers from Netflix, Apple, and Snowflake, Iceberg provides a high-performance, scalable way to organize, version, and manage datasets stored across cloud storage like S3. Its key benefits include:

• Schema Evolution & Compatibility: Ability to change schemas without disrupting ongoing operations.
