pub type ParquetColumnIndex = Vec<Vec<ColumnIndexMetaData>>;Expand description
Page level statistics for each column chunk of each row group.
This structure is an in-memory representation of multiple ColumnIndex
structures in a parquet file footer, as described in the Parquet PageIndex
documentation. Each ColumnIndex holds statistics about all the pages in a
particular column chunk.
column_index[row_group_number][column_number] holds the
ColumnIndex corresponding to column column_number of row group
row_group_number.
For example column_index[2][3] holds the ColumnIndex for the fourth
column in the third row group of the parquet file.
