alamb opened a new issue, #14831: URL: https://github.com/apache/datafusion/issues/14831
### Describe the bug This is a report from @lmwnshn As part of a series of issues that were discovered at CMU while working on DataFusion - https://github.com/apache/datafusion/issues/14373 Basically they found that DataFusion couldn't run substrait generated by Apache Calcite Quoting the readme: https://github.com/lmwnshn/15799-s25-project1-remnants/blob/main/README.md The idea behind this project was to: 1. Convert SQL to a Substrait plan with Calcite. 2. Execute the Substrait plan on different systems (e.g., DuckDB, DataFusion). Students would then experiment with Calcite's different rules. However, this project idea didn't quite work for the following reasons: 1. substrait-java does not run optimizations - while in theory this can be enabled, I recall running into some issues. 2. More critically, at the time of writing, both DuckDB and DataFusion have limited support for executing the Substrait generated by Calcite. ### To Reproduce See the code at https://github.com/lmwnshn/15799-s25-project1-remnants Note I haven't looked at any of this myself so I won't be able to help with specific questionds ### Expected behavior datafusion should work for all the plans ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
