Struct BackfillJob

Source

pub struct BackfillJob {
    pub table: TableIdent,
    pub text_column: String,
    pub new_col: VectorColSpec,
    pub embed_fn: EmbedFn,
    pub batch_size: usize,
    pub on_progress: Option<BackfillProgressFn>,
}

Expand description

Adds a new vector column to all existing files in a table.

Does not touch files that already have the column (idempotent). Concurrent new writes (after add_vector_column was called) already include the column and are also skipped.

Fields§

§table: TableIdent§text_column: String

Column in the Parquet files that holds the text to embed.

§new_col: VectorColSpec

Specification for the new vector column.

§embed_fn: EmbedFn

Callable: given a slice of text strings, returns one F32 vector per text.

§batch_size: usize

How many texts to embed per embed_fn call.

§on_progress: Option<BackfillProgressFn>

Optional progress callback.

where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync> ⓘ

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
