ChunkVariant

Enum ChunkVariant 

Source
pub enum ChunkVariant {
    Flat(DataChunk),
    Factorized(FactorizedChunk),
}
Expand description

A chunk that can be either flat (DataChunk) or factorized (FactorizedChunk).

Variants§

§

Flat(DataChunk)

A flat chunk with all rows materialized.

§

Factorized(FactorizedChunk)

A factorized chunk with multi-level representation.

Implementations§
