Hi all, I am pretty new to Parquet and trying to learn Parquet structure.
I assume that min, max and etc information has been stored for both ColumnMetaData and also DataPageHeader since 1.6.0 ( https://github.com/Parquet/parquet-mr/pull/338) I see the statistics in ColumnMetaData is used to filter blocks (or row groups) as filter2 at RowGroupFilter by calling canDrop(). I though the statistics in DataPageHeader is used to not to read a page by reading the statistics. However, my question is, I could not find where to use statistics in DataPageHeader for filter1 and also filter2. Could you give me some comments on this please?
