Learn about the journey of creating WarehousePG, an open source fork of Greenplum Database, in this 27-minute conference talk from the Open Lakehouse and AI Berlin Meetup. Discover the two-decade history of both WarehousePG and Greenplum Database, which are both PostgreSQL forks, and understand the circumstances that led to creating this new open source project after the upstream project became closed source. Explore the technical and legal challenges encountered during the open sourcing process, including navigating Contributor License Agreements (CLAs) and understanding the implications of PostgreSQL and Apache Licenses for the project's future development and community contributions.
