Struct StoreConfig 

pub struct StoreConfig {
    pub name: String,
    pub storage: StorageType,
    pub max_history: Option<u32>,
    pub max_age: Option<Duration>,
    pub max_bytes: Option<i64>,
    pub num_replicas: Option<usize>,
    pub discard: DiscardPolicy,
}

Configuration for creating a store.

Fields

name: String

Store name/bucket identifier.

storage: StorageType

Storage type (memory or persistent).

max_history: Option<u32>

Maximum history/versions to keep (NATS-specific, ignored by other stores).

max_age: Option<Duration>

Maximum age for entries in the bucket (bucket-level TTL). Entries older than this are automatically removed. NATS: maps to max_age on bucket config.

max_bytes: Option<i64>

Maximum bytes for the bucket (required by Synadia Cloud). NATS: maps to max_bytes on bucket config.

num_replicas: Option<usize>

Number of stream replicas for the bucket (NATS cluster mode). Defaults to 1 (single replica). Set to 3 for production HA clusters.

discard: DiscardPolicy

Behavior at max_bytes (NATS-specific, ignored by other stores). Defaults to DiscardPolicy::New (reject) so config buckets never silently drop a live value; set DiscardPolicy::Old for size-bounded log buckets (routing origins) that must never freeze writers. Only applied at bucket creation — an existing bucket’s policy is left untouched.
