Struct ThresholdSkewRule

Source

pub struct ThresholdSkewRule { /* private fields */ }

Expand description

Detects hot partitions whose input_rows exceeds threshold × median_rows.

Implementations§

Source §

impl ThresholdSkewRule

Source

pub fn new(threshold: f64) -> Self

Create a rule that flags partitions exceeding threshold × median input rows.

Typical value: 2.0 (flag anything more than 2× the median).
