Struct PromqlTuning 

pub struct PromqlTuning {
    pub max_samples: usize,
    pub lookback_delta_ms: i64,
    pub max_points_per_series: usize,
}

Tuning knobs for PromQL reads over stored timeseries data.

Fields

max_samples: usize

Stored rows one PromQL request can load. A request that needs more fails with an error. It never returns a truncated result.

lookback_delta_ms: i64

How far back an instant selector looks for a sample, in milliseconds.

max_points_per_series: usize

Points one series of a range query can hold. A finer step fails.
