Fields

columns: Vec<ColumnChunk>

Metadata for each column chunk in this row group. This list must have the same order as the SchemaElement list in FileMetaData.

total_byte_size: i64

Total byte size of all the uncompressed column data in this row group *

num_rows: i64

Number of rows in this row group *

sorting_columns: Option<Vec<SortingColumn>>

If set, specifies a sort ordering of the rows in this RowGroup. The sorting columns can be a subset of all the columns.

file_offset: Option<i64>

Byte offset from beginning of file to first page (data or dictionary) in this row group *

total_compressed_size: Option<i64>

Total byte size of all compressed (and potentially encrypted) column data in this row group *

ordinal: Option<i16>

Row group ordinal in the file *
