Struct DispatcherConfig 

pub struct DispatcherConfig {
    pub recall_fallback_threshold: f32,
    pub max_fallbacks: usize,
    pub weight_refresh_interval: u64,
    pub enabled_families: BTreeSet<IndexFamily>,
}

Configuration for the optimizer dispatcher brain.

Fields

recall_fallback_threshold: f32

Recall threshold below which a query is re-issued against the next-best index. Value is in [0.0, 1.0].

max_fallbacks: usize

Maximum number of fallback re-issues per query.

weight_refresh_interval: u64

After this many observations, refresh the cost-model weights from accumulated QueryStats.

enabled_families: BTreeSet<IndexFamily>

Set of families the dispatcher is allowed to consider. An empty set is interpreted as “all families”.
