Struct differential_dataflow::Config

source · [−]

pub struct Config {
    pub idle_merge_effort: Option<isize>,
}

Expand description

Configuration options for differential dataflow.

Fields

idle_merge_effort: Option<isize>

An amount of arrangement effort to spend each scheduling quantum.

The default value of None will not schedule operators that maintain arrangements other than when computation is required. Setting the value to Some(effort) will cause these operators to reschedule themselves as long as their arrangemnt has not reached a compact representation, and each scheduling quantum they will perform compaction work as if effort records had been added to the arrangement.

Implementations

impl Config

pub fn idle_merge_effort(self, effort: Option<isize>) -> Self

Assign an amount of effort to apply to idle arrangement operators.
