Apache Cloudberry: sovereignty score and 8 European alternatives

Apache Cloudberry is an open-source massively parallel processing (MPP) database that can serve as a data warehouse for large-scale analytics and AI or machine-learning workloads. It is derived from the open-source version of Greenplum Database and built on a modern PostgreSQL kernel, and it keeps operational compatibility with Greenplum so that existing users can migrate with familiar tooling. The software is released under the Apache License 2.0 and runs on standard hardware, virtual machines or in the cloud.

The project is developed under the Apache Software Foundation, a US 501(c)(3) non-profit, and is currently in incubation. Cloudberry states that it is not affiliated with Broadcom, which holds the Greenplum trademark, and it offers an open alternative to commercial Greenplum and other proprietary MPP warehouses. Because the database is installed and operated by the user, the location of data follows the deployment the organisation chooses. For a European buyer, the main questions are who operates the cluster and where its storage and backups are kept.

Why digital sovereignty matters with Apache Cloudberry

Apache Cloudberry is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Apache Cloudberry hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Apache Cloudberry is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Apache Cloudberry together with your other vendors and gives a total score, a heatmap and the main risk drivers.
