You mean the below code
```
parquet_path = f"dbg/index.parquet"
with pq.ParquetWriter(parquet_path, schema, compression='snappy',
filesystem=s3_fs) as w:
for batch in batches:
b = pa.RecordBatch.from_pydict(batch, schema=schema)
w.write_batch(b)
```
would commit even if an exception is thrown? I'm not sure what's the right
way to "close" the file handle without committing any partially written results
to s3.
