Struct parquet_format_async_temp::PageLocation

pub struct PageLocation {
    pub offset: i64,
    pub compressed_page_size: i32,
    pub first_row_index: i64,
}

Fields

offset: i64

Offset of the page in the file *

compressed_page_size: i32

Size of the page, including header. Sum of compressed_page_size and header length

first_row_index: i64

Index within the RowGroup of the first row of the page; this means pages change on record boundaries (r = 0).
