**Describe the bug** While testing the tpchgen-rs upgrade to arrow 57 in - https://github.com/clflushopt/tpchgen-rs/pull/200 @clflushopt, @kevinjqliu and I found that arrow-rs 57 seems to write data around 10% slower than arrow 56: https://github.com/clflushopt/tpchgen-rs/pull/200#pullrequestreview-3413005193 Specifically running this command is around 10% slower ```shell tpchgen-cli --scale-factor=100 --tables=lineitem --parts=10 --format=parquet ``` 56.0.0 takes 0m27.122s 57.0.0 takes 0m28.776s **To Reproduce** rm -rf lineitem && cargo build --release && time ./target/release/tpchgen-cli --scale-factor=100 --tables=lineitem --parts=10 --format=parquet **Expected behavior** 57 should be the same or better performance as 56 **Additional context** I am doing some git bisecting to see if I can find some more data -- This is an automated message from the Apache Git Service.
