crepererum opened a new issue #257: URL: https://github.com/apache/arrow-rs/issues/257
**Describe the bug** This property (that can be set via the `WriterPropertiesBuilder`): https://github.com/apache/arrow-rs/blob/508f25c10032857da34ea88cc8166f0741616a32/parquet/src/file/properties.rs#L99 can only be retrieved using this getter: https://github.com/apache/arrow-rs/blob/508f25c10032857da34ea88cc8166f0741616a32/parquet/src/file/properties.rs#L132-L135 but this getter is never used. In fact quickly trying out this property has no effect. I think it should probably we wired up here: https://github.com/apache/arrow-rs/blob/508f25c10032857da34ea88cc8166f0741616a32/parquet/src/arrow/arrow_writer.rs#L80-L101 where the incoming `RecordBatch` is split into batches of the configured size that will then fed into individual record batches. **To Reproduce** Steps to reproduce the behavior: 1. create a `RecordBatch` with 3 rows. 2. Set `WriterProperties.max_row_group_size` to 1 3. Create a parquet file 4. See the that parquet file has only 1 row group (should be 3). **Expected behavior** Record batches created from arrow should respect `WriterProperties.max_row_group_size`. **Additional context** Commit in question is `508f25c10032857da34ea88cc8166f0741616a32`. -- This is an automated message from the Apache Git Service.
