How we made WarehousePG Open Source (again)
Presented by:
Andreas Scherbaum
Andreas Scherbaum has been working with PostgreSQL since 1997. He is involved in several PostgreSQL related community projects, member of the Board of Directors of the European PostgreSQL User Group and also wrote a PostgreSQL book (in German).
Since 2011 he was working for EMC/Greenplum/Pivotal and tackled very big databases. Until 2024 he was doing the same - but with maybe even more and bigger databases - for Adjust GmbH in Berlin.
Now he's working at EDB and helping customers with even larger databases.
No video of the event yet, sorry!
WarehousePG is an Open Source fork of Greenplum Database, which by itself is a fork of PostgreSQL. The project was born after the upstream project was made closed source.
This talk gives an overview of the history of both projects, which already spans more than two decades. We then dive into the reasons for creating a fork, and all the stumbling stones we had to pass in order to make this project open source again. We also talk about the challenges of CLAs (Contributor License Agreements) and what implications the PostgreSQL and Apache Licenses have for the project.
