Contributing to Dremio

Thank you for your interest in contributing to Dremio.

This document summarizes the different ways you can contribute.

Feature requests and bug reports

If you believe you have found an issue in Dremio, or have an idea for a feature missing in our software, you might not be alone. Please start by searching https://community.dremio.com and check if someone else has already reported it.

If you're the first one to report a bug, please include as much information as possible, so we can diagnose and possibly reproduce:

• Dremio version, available under Help > About Dremio (please try to reproduce the issue with the latest available version, as it might have already been fixed)
• OS (uname -a output on Unix platforms, or equivalent for Windows)
• Java version (java -version)
• Information about the query: the query itself, the query profile, the data sources, and any other information you can provide that might be helpful
• If queried data is public, a link to it
• Stacktrace from the logs

For a feature request, please create a new topic describing the feature, what it is supposed to do, and why you need it. If someone else already created a topic for it, please contribute to the discussion.

Contributing code and documentation changes

Here are the recommended steps if you are ready to contribute code or a documentation change:
