I'm seeing the same problem, it may not be a memory leak, I believe [this](https://github.com/apache/arrow/blob/cfbbf708082c84f3a7cb1246d83ef134c2ac27c4/cpp/src/arrow/dataset/dataset_writer.h#L33) is the culprit: an 8 million row queue with no way to control the size. The fix that works is to just flush / write to separate Parquets, at a few GB each. If you feed those into DuckDB, it's fine taking in a set of Parquets. -- This is an automated message from the Apache Git Service.
