Deep.BI provides extended support for Apache Druid by maintaining patched releases. These patched versions include security patches, critical bug fixes, and improvements. All patches are designed to be fully compatible with the corresponding upstream Apache Druid release. No functionality is removed or broken.
Releases are published here: Deep.BI Druid Releases on GitHub
Starting with Apache Druid 33.0.x, patched releases use the format <druid-version>-deepbiN (for example: 33.0.0-deepbi1). For Apache Druid versions up to 32.0.x, the format <druid-version>-patchN was used (for example: 30.0.1-patch3).
Each new patched release in a given line is cumulative, meaning that the latest patch includes all fixes from earlier patches of the same base version.
Patched releases contain security updates, critical bug fixes, and stability or performance improvements that preserve API and query compatibility. They do not introduce experimental features, breaking changes, or modifications to user-facing functionality. This ensures that upgrading to a patched release does not require application-level changes.
Deep.BI maintains patched releases for the latest three upstream Apache Druid versions. Older versions are updated only under a commercial support agreement. For long-term maintenance beyond this window, contact druid@deep.bi.
Every release is tested by starting a full Druid cluster, ingesting sample data, verifying the APIs, and running queries in both native and MSQ execution modes to confirm correctness and stability.
Patched releases are drop-in replacements for the matching Apache Druid version. Upgrading requires no intermediate steps and rolling upgrades work the same way as in the upstream release.
- Stay on your current major release with patches if you need maximum stability and cannot upgrade due to dependencies or operational constraints.
- Upgrade to the latest patched release in your major line to ensure you have all security and stability fixes.
- Move to a newer major release if you want access to upstream features and improvements introduced since your current version. Always use the patched variant of the chosen release line.
