Struct JoinStats 

pub struct JoinStats {
    pub build_records: u64,
    pub build_nulls: u64,
    pub duplicates: u64,
    pub probe_records: u64,
    pub matches: u64,
    pub misses: u64,
    pub project_misses: u64,
}

Running counters for a join, mirroring the faucet_join_* metrics.

Fields

build_records: u64

Records ingested by the build side (before null-key skipping).

build_nulls: u64

Build records skipped because their key resolved to null/absent.

duplicates: u64

Distinct build keys that appeared more than once (duplicate keys).

probe_records: u64

Records ingested by the probe side.

matches: u64

Probe records that matched at least one build record.

misses: u64

Probe records with no build-side match.

project_misses: u64

Projections skipped because the from path was absent on the build record.
