Hi all, A regression was encountered [1] while updating the arrow-cpp conda-forge feedstock for Arrow 19.0.1. The proximate issue may be that conda-forge doesn't do unity builds and our CI didn't catch the ultimate issue which appears to be a missing include.
Can others please take a look at the linked pull request and help assess whether we need to issue a patch release to address this? Note, the feedstock may be fixable with a patch and I've filed an issue [2] to address it on our end. Thanks [1] https://github.com/conda-forge/arrow-cpp-feedstock/pull/1706#issuecomment-2661687327 [2] https://github.com/apache/arrow/issues/45545
