- state: Literal['DEPENDENCIES_UNREADY', 'PENDING_CREATION', 'ALIVE', 'RESTARTING', 'DEAD']#
The state of the actor.
DEPENDENCIES_UNREADY: Actor is waiting for dependency to be ready. E.g., a new actor is waiting for object ref that’s created from other remote task.
PENDING_CREATION: Actor’s dependency is ready, but it is not created yet. It could be because there are not enough resources, too many actor entries in the scheduler queue, or the actor creation is slow (e.g., slow runtime environment creation, slow worker startup, or etc.).
ALIVE: The actor is created, and it is alive.
RESTARTING: The actor is dead, and it is restarting. It is equivalent to
PENDING_CREATION
, but means the actor was dead more than once.DEAD: The actor is permanatly dead.
- node_id: str | None#
The node id of this actor. If the actor is restarting, it could be the node id of the dead actor (and it will be re-updated when the actor is successfully restarted).
- death_cause: dict | None = None#
Actor’s death information in detail. None if the actor is not dead yet.
