Struct DistributedWorkUnitFeedContext

Source

pub struct DistributedWorkUnitFeedContext {
    pub fan_out_tasks: usize,
}

Expand description

Provides contextual information about where a WorkUnitFeedProvider is being executed. When using WorkUnitFeedProvider in distributed queries, it might be getting executed in the coordinating stage, or it might be getting executed just locally because the query did not need any remote execution.

Fields§

§fan_out_tasks: usize

The number of distributed tasks to which the WorkUnitFeedProvider should fan out.
