Struct OffsetIndexMetaData

Source
pub struct OffsetIndexMetaData {
    pub page_locations: Vec<PageLocation>,
    pub unencoded_byte_array_data_bytes: Option<Vec<i64>>,
}
Expand description

OffsetIndex information for a column chunk. Contains offsets and sizes for each page in the chunk. Optionally stores fully decoded page sizes for BYTE_ARRAY columns.

See ParquetOffsetIndex for more information.

Fields§

§page_locations: Vec<PageLocation>

Vector of PageLocation objects, one per page in the chunk.

§unencoded_byte_array_data_bytes: Option<Vec<i64>>

Optional vector of unencoded page sizes, one per page in the chunk. Only defined for BYTE_ARRAY columns.
