Struct scylla::transport::speculative_execution::PercentileSpeculativeExecutionPolicy

pub struct PercentileSpeculativeExecutionPolicy {
    pub max_retry_count: usize,
    pub percentile: f64,
}

A policy that triggers speculative executions when the request to the current host is above a given percentile.

Fields

max_retry_count: usize

The maximum number of speculative executions that will be triggered for a given request (does not include the initial request)

percentile: f64

The percentile that a request’s latency must fall into to be considered slow (ex: 99.0)
