URL: https://github.com/apache/arrow/issues/14837
### Describe the bug, including details regarding any error messages,
version, and platform.
When I am using pq.write_to_dataset (
existing_data_behavior='overwrite_or_ignore') is able to add data
Why is the use of ds.write_dataset ( existing_data_behavior =
'overwrite_or_ignore') an overlay?
```
df = pd.DataFrame({'one': [-1, 3, 2.5, 2.5, 2.5],
'two': ['foo', 'bar', 'baz', 'foo', 'foo'],
'three': [True, False, True, False, True],
'four': [datetime.date(2021, 1, 3), datetime.date(2021,
3, 1), datetime.date(2021, 1, 1),
datetime.date(2021, 3, 11), datetime.date(2021,
4, 1)]
},
index=list('abcde'))
table = pa.Table.from_pandas(df, preserve_index=True)
```
**pq.write_to_datase**
```
pq.write_to_dataset(table, root_path=root_path,
# existing_data_behavior='delete_matching',
existing_data_behavior='overwrite_or_ignore',
use_legacy_dataset=False
)
```
**ds.write_dataset**
```
ds.write_dataset(table, root_path,
# existing_data_behavior='delete_matching',
existing_data_behavior='overwrite_or_ignore',
format="parquet")
