Thang Long Vu updated SPARK-47731:
----------------------------------
Description:
Parquet reader in Spark has a bug where a file containing 2b+ rows in a single
rowgroup causes it to run out of the `Integer` range. This prevents Delta
Parquet readers from exposing the row_index field as a metadata field.
It would be great to have this fix so that we can use 2b+ rows in a single
rowgroup and also to safely allow row_index field to be used in the Delta
Parquet readers for any functionalities that might depend on it.
