Apache Hudi: sovereignty score and 8 European alternatives

Apache Hudi is an open data lakehouse platform that adds database functionality to data lakes while keeping data in open file formats. It supports tables, transactions, upserts and deletes, indexes, clustering and compaction, as well as incremental processing for streaming and batch workloads. It is a software library rather than a hosted service: you run it inside your own data platform.

Hudi was developed at Uber, open-sourced in 2017 and has been a top-level project of the Apache Software Foundation, a US non-profit organisation, since 2020. It is licensed under the Apache License 2.0. Because Hudi has no hosting of its own, you decide where data and metadata live: in your own data centre or with a European storage and cloud provider. Open source code and an open table format limit lock-in, and with it dependence on a single supplier or jurisdiction.

Why digital sovereignty matters with Apache Hudi

Apache Hudi 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 Hudi hosts data in EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Apache Hudi 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 Hudi together with your other vendors and gives a total score, a heatmap and the main risk drivers.
