Struct AppState 

pub struct AppState<E> {
    pub engine: Arc<E>,
    pub ingest_limits: IngestLimits,
    pub ready: Arc<AtomicBool>,
    pub stream: Arc<StreamHub>,
}

All-in-one single-process composition for a backend that serves every store capability. Split deployments construct the narrower capability states directly.

Fields

engine: Arc<E>

Backend that implements every store capability.

ingest_limits: IngestLimits

Limits enforced by the ingest service before writing.

ready: Arc<AtomicBool>

Gates ingest (writes) only. Query and compact remain available during drains so that in-flight reads can complete while the worker sheds write traffic.

stream: Arc<StreamHub>

Shared fan-out hub for store.stream.v1.Subscribe.
