Expand description

Responses that Controller can produce.

Variants§

§

PeekResponse(UuidPeekResponseOpenTelemetryContext)

The worker’s response to a specified (by connection id) peek.

Additionally, an OpenTelemetryContext to forward trace information back into coord. This allows coord traces to be children of work done in compute!

§

SubscribeResponse(GlobalIdSubscribeResponse<T>)

The worker’s next response to a specified subscribe.

§

ComputeReplicaHeartbeat(ReplicaIdDateTime<Utc>)

Notification that we have received a message from the given compute replica at the given time.

§

ComputeReplicaMetrics(ReplicaIdVec<ServiceProcessMetrics>)

Notification that new resource usage metrics are available for a given replica.

§

ComputeReplicaWriteFrontiers(BTreeMap<ReplicaId, Vec<(GlobalId, T)>>)

Notification that the write frontiers of the replicas have changed.
