timsaucer opened a new issue, #1144: URL: https://github.com/apache/datafusion-python/issues/1144
**Describe the bug** During testing of the initial implementation of FFI user defined window functions, I generated a panic in `partition_evaluator`. **To Reproduce** Open `examples/datafusion-ffi-example/src/window_udf.rs` Change this to use `lead_udwf()` instead of `rank_udwf()`. Run integration test in `examples/datafusion-ffi-example/python/tests/_test_window_udf.py` **Expected behavior** Should not panic. **Additional context** It is unclear if the problem is in datafusion-python, or more likely upstream. -- This is an automated message from the Apache Git Service.
