Re: [PR] Bug Fix: Position Deletes + row_filter yields less data when the DataFile is large [iceberg-python]
kevinjqliu commented on PR #1141:
URL: https://github.com/apache/iceberg-python/pull/1141#issuecomment-2350674380
> In cases where a single RecordBatch -> a Table -> multiple RecordBatches because of how Arrow automatically chunks a Table into multiple RecordBatches, we would lose the remaining RecordBatches in the returned output. Essentially, there's no guarantee that a single RecordBatch will remain a single one in a round trip conversion to Arrow Table, and back.
This is specifically about this piece of code?
```
batch = arrow_table.to_batches()[0]
```
