Struct BackfillConfig 

pub struct BackfillConfig {
    pub batch_size: usize,
    pub max_concurrent: usize,
    pub dual_write: bool,
    pub target_query_threshold: f64,
    pub rollback_window_secs: u64,
}

Configuration for the backfill coordinator.

Controls batch sizing, caller-managed concurrency, routing, and rollback timing. See docs/backfill.md for default values and policy semantics.

Fields

batch_size: usize

dual_write: bool

Whether new documents should be dual-written during migration.

target_query_threshold: f64

Raw progress threshold at which query routing may choose the target model.

rollback_window_secs: u64

Seconds to retain both write models after a completed cutover.
