Page index is a pretty new concept in the history of parquet specs. In the old days when page index is unavailable, the I/O unit is always column chunk because we can only drop row groups based on the column statistics. Once page index is supported, finer-grained I/O unit is a must if we want to leverage page index to efficiently skip specific pages. @XinyuZeng -- This is an automated message from the Apache Git Service.
