Hello thanks for the detailed report!
I am able to reproduce the issue, my times are overall a bit faster (192ms
for 9.0.0 read) but 192ms -> 5s is still an unacceptable regression.
```
r$> packageVersion('arrow')
microbenchmark::microbenchmark(
arrow::read_parquet(file, col_select = 1:200), times = 10
)
[1] '11.0.0.2'
Unit: seconds
expr min lq mean
median uq max neval
arrow::read_parquet(file, col_select = 1:200) 5.736177 5.993478 6.068209
6.093701 6.165921 6.355394 10
```
