Hi Arrow Devs, I'm a maintainer of a project called cuDF (https://github.com/rapidsai/cudf.git) that is based on the Arrow columnar format and depends on the Arrow C++ and Python libraries. Currently, we are pinned to version `1.0.1`, but we've gotten feedback from the community that they'd really like us to upgrade to the latest version. We tried to upgrade to version `3.0.0` but ran into a major issue:
- GPU buffer validation fails in array and table creation code flows. Related JIRA is https://issues.apache.org/jira/browse/ARROW-11872 and subsequent PR fixing the issue is https://github.com/apache/arrow/pull/9640 and was merged a few days ago. Unfortunately, this effectively blocks most usage of Arrow libraries for CUDA projects. - After this, we tried version `2.0.0` but hit a different issue of round-tripping of list of structs columns doesn't work properly in the parquet reader and writer. This is fixed in version `3.0.0`. It seems like version `4.0.0` is tentatively scheduled for June 2021, which is unfortunately quite a bit away. Would it be possible to do a patch release in `3.x` that included the fix for GPU buffer validation? This would greatly help us upgrade to the latest arrow version and directly help users using both Arrow and cuDF. Regards, Prem
