Trait FactorizedData

Source

pub trait FactorizedData: Send + Sync {
    // Required methods
    fn chunk_state(&self) -> &ChunkState;
    fn logical_row_count(&self) -> usize;
    fn physical_size(&self) -> usize;
    fn is_factorized(&self) -> bool;
    fn flatten(&self) -> DataChunk;
    fn as_factorized(&self) -> Option<&FactorizedChunk>;
    fn as_flat(&self) -> Option<&DataChunk>;
}

Expand description

Trait for data that can be in factorized or flat form.

This provides a common interface for operators that need to handle both representations without caring which is used. Inspired by LadybugDB’s unified data model.

§Example

fn process_data(data: &dyn FactorizedData) {
    if data.is_factorized() {
        // Handle factorized path
        let chunk = data.as_factorized().unwrap();
        // ... use factorized chunk directly
    } else {
        // Handle flat path
        let chunk = data.flatten();
        // ... process flat chunk
    }
}
