Struct TranscodeBudget 

pub struct TranscodeBudget {
    pub max_rows: u64,
    pub segment_rows: u64,
    pub size_floor_rows: u64,
}

Knobs for a checkpoint emission.

Fields

max_rows: u64

Maximum rows this checkpoint may transcode into columnar segments. A checkpoint always completes: rows beyond the budget are deferred.

segment_rows: u64

Rows per emitted segment (the last segment may be shorter).

size_floor_rows: u64

Size floor: if the un-materialized tail up to the checkpoint boundary is smaller than this, materialization is skipped this round — the tail stays visible through the row path, so correctness is unaffected while bookkeeping is saved (ADR 0069 §6).
