There was a problem hiding this comment.
I think you should also update line 405 below (cudf::detail::gather call) to pass it the same stream.

This PR was opened during burndown, so really it should target branch-0.19. In this case it's probably safe, but please be careful in the future. |

Small PR to provide two fixes:
rmm::device_uvectorin place ofdevice_vectorto improve efficiency. This is a scratch space, so supplied stream and default memory resource is used. Part of [BUG] use device_uvector instead of device_vector when possible #5380sort_helper::grouped_valuedocstring to reflect change after use of stable sort.
