Yes, the PR (and issue) title is misleading. Originally I implemented this by checking the DataPageVersion solely, which is the same behavior of parquet-mr. Then after more investigation, I found that parquet-mr has mixed DataPageVersion with ParquetVersion. So I think it is better to check the ParquetVersion in the C++ implementation. Back to the question above: yes, the default encoding is switched to RLE when parquet version is 2.x and data page version is v1. Sorry for the confusion. I didn't know the default setting on the pyarrow side before this discussion. @jorisvandenbossche @pitrou -- This is an automated message from the Apache Git Service.
