Enum WorkloadClass 

pub enum WorkloadClass {
    Control,
    Replication,
    Oltp,
    InteractiveSql,
    AiRetrieval,
    Analytics,
    Maintenance,
    Backup,
}

The workload class of a unit of admitted work (spec section 10.5, S1E-001).

The variant set is exactly the spec’s; scheduling and memory-governance policy is derived from it. Serde form is the variant name, stable for cluster-settings replication.

Variants

Control

Node control plane (membership, catalog, health). Reserved capacity.

Replication

Replication traffic (log shipping, follower reads). Reserved capacity.

Oltp

Foreground point reads/writes.

InteractiveSql

Foreground ad-hoc SQL.

AiRetrieval

ANN/full-text candidate retrieval and scoring.

Analytics

Large scans and aggregations.

Maintenance

Compaction, GC, index rebuilds. Yields to foreground work (§13.1).

Backup

Backup and export.

Implementations

impl WorkloadClass

pub const ALL: [WorkloadClass; 8]

Every class, in declaration order.

pub fn name(self) -> &'static str

Stable lowercase name (matches the scheduler queue names of §13.1).

pub fn has_reserved_capacity(self) -> bool

Classes whose capacity is reserved and must never be fully starved (spec §13.1: “control and replication have reserved capacity”).

pub fn is_low_priority(self) -> bool

Deferrable classes: the first to be rejected and throttled under pressure (spec §13.1 maintenance yields to foreground work; §10.5 S1E-003 escalation step 1 rejects new low-priority work).

Trait Implementations
