Awesome, thanks! For your question, it seems like `write_dataset()` behaves differently on windows and ubuntu. In some cases row-order is kept on windows when `preserve_order = FALSE` (but not always). We can see this from the CI job when I had the test `expect_false(all(unordered_ds$x == df$x))`: it passed on ubuntu and windows with an older version of R, but failed on windows with a newer version of R (https://github.com/apache/arrow/actions/runs/22290480076/job/64535896168). I could reproduce this on my machine with R 4.5.2, with both ubuntu and windows. -- This is an automated message from the Apache Git Service.
