Indexes
Row Group Index
The row group indexes consist of a ROW\_INDEX stream for each primitive
column that has an entry for each row group. Row groups are controlled
by the writer and default to 10,000 rows. Each RowIndexEntry gives the
position of each stream for the column and the statistics for that row
group.
