### Describe the bug, including details regarding any error messages, version, and platform. DatasetWriter deadlocks when batch written is longer than max_rows_queued. https://github.com/apache/arrow/blob/e7ccca6917be3bf8be9c25e35bd6b2459e69be0b/cpp/src/arrow/dataset/dataset_writer.cc#L61C1-L61C10 When `values` argument of Acquire is greater than `max_values_` it causes forever pause. This was probably hidden so far because `max_rows_queued` cannot be modified using acero `write` node. I have already created [PR46139](https://github.com/apache/arrow/pull/46139) with the fix and according test. I have branch ready that adds `max_rows_queued` to `FileSystemDatasetWriteOptions`. I ended up not using this feature but LMK if I should create PR. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
