Hi All, We have recently had a lot of CI builds fail for Rust due to long compile times, this was first pointed out by Francois on the following PR: https://github.com/apache/arrow/pull/5303
However, it seems unrelated to this change as the following PR's are failing for the same reason also: https://github.com/apache/arrow/pull/5310 https://github.com/apache/arrow/pull/5309 I'm not sure what has changed (4 days ago I posted a PR that did not have this issue, https://github.com/apache/arrow/pull/5269) but it would seem that this increase might be due to updates to the nightly compiler, I will try to find out. Any other ideas? Paddy
