Struct EncodedPage

Source

pub struct EncodedPage {
    pub data: Vec<LanceBuffer>,
    pub description: PageEncoding,
    pub num_rows: u64,
    pub row_number: u64,
    pub column_idx: u32,
}

Expand description

An encoded page of data

Maps to a top-level array

For example, FixedSizeList will have two EncodedArray instances and one EncodedPage

Fields§

§data: Vec<LanceBuffer>§description: PageEncoding§num_rows: u64

The number of rows in the encoded page

§row_number: u64

The top-level row number of the first row in the page

Generally the number of “top-level” rows and the number of rows are the same. However, when there is repetition (list/fixed-size-list) there will be more or less items than rows.

A top-level row can never be split across a page boundary.

§column_idx: u32

The index of the column
