> Key: ARROW-13120
> URL: https://issues.apache.org/jira/browse/ARROW-13120
> Project: Apache Arrow
> Issue Type: Bug
> Components: Rust
> Reporter: Morgan Cassels
> Priority: Major
> Attachments: test.parquet
>
>
> This issue only occurs when the batch size < the number of rows in the table. The attached parquet `test.parquet` has 31430 rows and a single column containing string lists. This issue does not appear to occur for parquets with integer list columns.
