### Describe the bug, including details regarding any error messages, version, and platform. Dataset API gets stuck if one tries to read many columns (100k+) from a parquet or arrow file. The API works if the amount of columns is narrowed via projection. **Reproduction:** Use the code from the [example](https://arrow.apache.org/cookbook/java/dataset.html#constructing-datasets) and try to read a file with 100k columns. No batch will be loaded even if the batch size is 1. version: arrow-dataset 11.0 ### Component(s) Java -- This is an automated message from the Apache Git Service.
