Jorge Leitão created ARROW-13349:
------------------------------------
Summary: [C++][Parquet] num_rows is incorrect for nested types
Key: ARROW-13349
URL: https://issues.apache.org/jira/browse/ARROW-13349
Project: Apache Arrow
Issue Type: Bug
Components: C++, Parquet
Reporter: Jorge Leitão
Data pages v2 have:
* num_rows
* num_values
we write num_rows equal to the num_values. However, they represent different
aspects.
Given a list such as "[[0, 1], None, [2, None, 3]]", num_rows = 3 and
num_values = 6. We currently report 6 in both instances.
