@shangxinli, unfortunately we still struggle with not having proper low
level API for our clients. We did not add the ranges and such to the public API
because they should not be required there. Since both Spark and Hive uses lower
level APIs (that was not designed to be public originally) I don't think we
have any other choice for now to make all the necessary classes/methods public.
Meanwhile, I've added `RowRanges` to the package
`org.apache.parquet.internal.filter2.columnindex` (note `internal`) to make it
clear that even though the class is public it is not for our clients. So, if we
really want to make this public we also need to move it to another package.

> When rolling out to Presto, I found we need to know the boundaries of each
