Chunking

For quality metadata it can be important to break up text into smaller parts for both better metadata and retrieval. A chunker implements the ChunkerTransformer trait.

The ChunkerTransformer trait

Which is defined as follows:

pub trait ChunkerTransformer: Send + Sync + Debug {
    async fn transform_node(&self, node: IngestionNode) -> IngestionStream;

    /// Overrides the default concurrency of the pipeline
    fn concurrency(&self) -> Option<usize> {
        None
    }
}

Or in human language: “Given a Node, break it up into smaller parts”.
