}Expand description
Reschedule is for the Command::RescheduleFragment, which is used for rescheduling actors
in some fragment, like scaling or migrating.
Fields§
§added_actors: HashMap<WorkerId, Vec<ActorId>>Added actors in this fragment.
removed_actors: Vec<ActorId>Removed actors in this fragment.
vnode_bitmap_updates: HashMap<ActorId, Bitmap>Vnode bitmap updates for some actors in this fragment.
upstream_fragment_dispatcher_ids: Vec<(FragmentId, DispatcherId)>The upstream fragments of this fragment, and the dispatchers that should be updated.
upstream_dispatcher_mapping: Option<ActorMapping>New hash mapping of the upstream dispatcher to be updated.
This field exists only when there’s upstream fragment and the current fragment is hash-sharded.
downstream_fragment_ids: Vec<FragmentId>The downstream fragments of this fragment.
actor_splits: HashMap<ActorId, Vec<SplitImpl>>Reassigned splits for source actors.
It becomes the actor_splits in UpdateMutation.
Source and SourceBackfill are handled together here.
newly_created_actors: Vec<(StreamActor, PbActorStatus)>Trait Implementations§
