------------------------------
Reporter: Adam Lippai (was: Andy Grove)
> [Rust] [DataFusion] Query returns incorrect row count
> -----------------------------------------------------
>
> Key: ARROW-6687
> URL: https://issues.apache.org/jira/browse/ARROW-6687
> Project: Apache Arrow
> Issue Type: Bug
> Components: Rust, Rust - DataFusion
> Affects Versions: 0.15.0
> Reporter: Adam Lippai
> Priority: Major
>
> I received this bug report directly via email:
>
> Hi,
>
> I've just tried out the master branch of the arrow lib, the SQL interface for
> parquet file generated by pyarrow 0.14.1 and pandas 0.25.1
>
> It returns incorrect num_rows for my file (with ~3000columns x 2456rows),
> it's actually the batch size number 1024*1024 instead of the 2456 rows. The
> query is simple SELECT col FROM data and it's the sample code you've created
> and works for the test file in the arrow testing repo.
>
> Sorry for reporting the issue via mail, it was faster & easier this way.
>
> I'm super happy and grateful that you decided to add parquet support. This is
> an awesome project, keep up the good work!
>
> Best regards,
> Adam Lippai
