Enum WorkerToCoordinatorMsg

Source

pub enum WorkerToCoordinatorMsg {
    TaskMetrics(TaskMetrics),
    LoadInfo(LoadInfo),
    LoadInfoEos,
}

Variants§

§

TaskMetrics(TaskMetrics)

Sends the metrics collected during task execution back to the coordinator. This is sent after all partitions of a task have finished (or been dropped), ensuring metrics are never lost due to early stream termination. metrics[i] is the set of metrics for plan node i in pre-order traversal order.

§

LoadInfo(LoadInfo)

Load information reported by a task. This information is used for dynamically sizing the number of workers involved in a query.
