Sarah Gilmore created ARROW-14723:
-------------------------------------
Summary: [Python] pyarrow cannot import parquet files containing
row groups whose lengths exceed int32 max.
Key: ARROW-14723
URL: https://issues.apache.org/jira/browse/ARROW-14723
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 5.0.0
Reporter: Sarah Gilmore
Attachments: intmax32.parq, intmax32plus1.parq
It's possible to create Parquet files containing row groups whose lengths are
greater than int32 max (2147483647). However, Pyarrow cannot read these files.
{code:java}
>>> import pyarrow as pa
>>> import pyarrow.parquet as pq
# intmax32.parq can be read in without any issues
>>> t = pq.read_table("intmax32.parq");
$ intmax32plus1.parq cannot be read in
>>> t = pq.read_table("intmax32plus1.parq");

{code}
However, both files can be imported via the C++ Arrow bindings without any
issues.
