Came across this issue recently and I can still see this https://github.com/apache/arrow/issues/39808#issuecomment-2163183635 Previously I tried `pre_buffer=False` and `use_stream_buffer=True` in [`ParquetFragmentScanOptions` ](https://arrow.apache.org/docs/python/generated/pyarrow.dataset.ParquetFragmentScanOptions.html), in which the `total_allocated_bytes` stopped growing. There is also a new option `cache_metadata` in `to_batches` (not released yet; only dev version), which seems to reduce some %. However, the "memory usage" difference between dataset and ParquetFile is still quite big. -- This is an automated message from the Apache Git Service.
