Struct ContinuousAggregateDef

    pub name: String,
    pub source: String,
    pub bucket_interval: String,
    pub bucket_interval_ms: i64,

}

Definition of a continuous aggregate.

Map-encoded so fields (e.g. database_id) can be added with #[msgpack(default)] and older persisted definitions still decode without a migration.

Fields

database_id: u64

Owning database. Scopes the Data-Plane manager’s per-name maps and catalog keys so an aggregate named identically in two databases never collides or materializes against the wrong database’s storage.

#[msgpack(default)]: definitions persisted before database scoping decode with 0 (DatabaseId::DEFAULT) — the database those legacy rows lived in — so no migration is required.

name: String

Name of this aggregate (e.g., “metrics_1m”).

source: String

Source collection or aggregate to read from.

bucket_interval: String

Time bucket interval string (e.g., “1m”, “1h”, “1d”).

bucket_interval_ms: i64

Bucket interval in milliseconds (computed from bucket_interval).

group_by: Vec<String>

Columns to GROUP BY (tag/symbol columns).

aggregates: Vec<AggregateExpr>

Aggregate expressions to compute.

refresh_policy: RefreshPolicy

When to refresh.

retention_period_ms: u64

Retention period in milliseconds (0 = infinite, independent of source).

stale: bool

Whether this aggregate is currently stale (schema change invalidation).
