pitrou opened a new issue, #36892: URL: https://github.com/apache/arrow/issues/36892
### Describe the bug, including details regarding any error messages, version, and platform. I did not pay attention initially, but it seems https://github.com/apache/arrow/pull/35197 introduced a large regression on the [wide-dataframe benchmark](https://github.com/voltrondata-labs/benchmarks/blob/main/benchmarks/wide_dataframe_benchmark.py). See benchmark results here: https://conbench.ursa.dev/compare/runs/9cf73ac83f0a44179e6538b2c1c7babd...3d76cb5ffb8849bf8c3ea9b32d08b3b7/ Note the benchmark is creating a dataframe with 10000 columns. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
