Struct RowPoolStatistics

    pub total_generated: u64,

    pub peak_active: u64,

}

Summary statistics for the row pool at the end of a training run.

Carried inside TrainingOutput and written to training/timing/cut_stats.parquet.

Fields

total_generated: u64

Total number of rows generated over the entire training run.

total_active: u64

Number of rows still active in the pool at the end of training.

peak_active: u64

Highest number of active rows observed at any point during training.

cuts_active: u64

Total rows currently active in the LP.

rows_in_lp_total: u64

Sum, over every lazy-selection LP solve in the run, of the resident row count loaded into that solve (reduced across ranks). With Self::rows_in_lp_solve_count this gives the mean rows-in-LP per solve. Zero when no lazy selection ran (the resident-subset solve path was never taken), letting consumers distinguish “not applicable” from “zero rows”.

rows_in_lp_solve_count: u64

Number of lazy-selection LP solves in the run (reduced across ranks); the denominator for the mean rows-in-LP. Zero when no lazy selection ran.

rows_in_lp_max: u64

Largest resident row count loaded into any single lazy-selection LP solve over the run (reduced across ranks). Zero when no lazy selection ran.

total_loaded: u64

Rows loaded from a boundary policy rather than generated by this run; a subset of Self::total_generated. Zero when no boundary policy loaded.
