Antoine Pitrou commented on ARROW-17100:
----------------------------------------
That changeset is ARROW-10353, which fixes bugs both in the read and write path
for V2 data pages. On the write side, Parquet C++ used not to always set
{{is_compressed = false}} in the data page, regardless of compression. On the
read side, Parquet C++ used to always decompress, regardless of the
{{is_compressed}} flag.
> [C++][Parquet] Fix backwards compatibility for ParquetV2 data pages written
