The sorting done by orderby is not stable. This means, given the input: a | b --- | --- 1 | false 1 | true the test could have generated both `[false, true]` and `[true, false]` for the `b` column. We likely did not encounter this before https://github.com/apache/arrow/commit/498b645e1d09306bf5399a9a019a5caa99513815 because the entire thing was run serially (even though there was a `parallel` option it was not setup correctly). Now that things are properly running parallel the results are non-deterministic. We could remove the `b` column but I feel it is a better stress test to have at least one payload column. So I changed the test to only compare the key array and not the payload array. -- This is an automated message from the Apache Git Service.
