Struct Worker 

pub struct Worker {
    pub worker_id: String,
    pub pool_id: String,
    pub cell_id: Option<String>,
    pub status: WorkerStatus,
    pub last_heartbeat_at: DateTime<Utc>,
    pub capacity_json: Option<Value>,
    pub created_at: DateTime<Utc>,
    pub updated_at: DateTime<Utc>,
}

Registered Chronon worker instance (heartbeat).

Workers register at startup and send periodic heartbeats so coordinators can detect stale capacity and route claims to live pools.

Fields

worker_id: String

Stable worker instance id.

pool_id: String

Execution pool this worker serves (matches Run::pool_id).

cell_id: Option<String>

Optional placement cell / availability zone label.

status: WorkerStatus

Whether the worker accepts new claims.

last_heartbeat_at: DateTime<Utc>

Last heartbeat timestamp (updated by SchedulerStore::heartbeat_worker).

capacity_json: Option<Value>

Opaque capacity hints (concurrency limits, CPU, etc.).

created_at: DateTime<Utc>

Row creation time.

updated_at: DateTime<Utc>

Last metadata update.
