Dremio OSS

Dremio is a data analytics platform aimed at organizations that want to query and analyze large volumes of data without first moving or copying it into a separate, dedicated analytics database. It positions itself as filling a gap between raw data storage and the tools people need to get value out of that data.

The open-source edition can be built and run locally, exposing a web UI at localhost:9047 once started, or installed as a production tarball for server deployment, with an embedded mode also available. Building it requires a specific combination of JDK versions (21 as default, with 17 and 11 configured in the Maven toolchain for certain tests) plus Maven, reflecting a substantial, enterprise-grade Java codebase.

The README notes that to provide the best possible experience, the build includes some dependencies distributed under non-open-source licenses, so the fully open-source experience may differ slightly depending on build configuration. Dremio is written in Java and the open-source edition is released under the Apache-2.0 license, with full documentation hosted separately.
