Struct IndexPolicy 

pub struct IndexPolicy {
    pub interval: Duration,
    pub backoff: u32,
    pub tail_threshold: u64,
    pub tail_deadline: Duration,
}

Pacing policy for one database’s background indexing job.

A publication is due when the adaptive floor has elapsed — the base interval stretched by a multiple of the previous publication’s duration, which bounds the indexing duty cycle as full republication gets slower — and the pending log tail is either large enough to be worth rewriting every index or old enough that deferring it further would leave cold readers and backups too far behind.

Every database starts from the node’s NodeConfig pacing fields; the catalog SetIndexPolicy RPC (or TransactorNode::set_index_policy) overrides it at runtime.

Fields

interval: Duration

Base interval between publications (NodeConfig::index_interval).

backoff: u32

Duty-cycle multiplier on the previous publication’s duration (NodeConfig::index_backoff).

tail_threshold: u64

Pending-datom count below which a due publication is deferred (NodeConfig::index_tail_threshold).

tail_deadline: Duration

Longest a below-threshold tail may defer publication (NodeConfig::index_tail_deadline).
