[−][src]Struct parquet_format::RowGroup
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 *
