Struct OrderingCostRow 

pub struct OrderingCostRow {
    pub ordering: String,
    pub scrub_reads: u64,
    pub scrub_bytes: u64,
    pub pan_reads: u64,
    pub pan_bytes: u64,
    pub total_reads: u64,
    pub total_bytes: u64,
    pub total_cost: u64,
    pub recommended: bool,
}

One ordering’s simulated cost (range reads + bytes read per query + totals).

Fields

ordering: String

scrub_reads: u64

scrub_bytes: u64

pan_reads: u64

pan_bytes: u64

total_reads: u64

total_bytes: u64

total_cost: u64

Blended cost the ranking uses: total_bytes + total_reads * gap.

recommended: bool
