Implementations

impl SlowQueryLogger

pub fn new(opts: SlowQueryOpts) -> Arc<Self>

pub fn for_destination( dest: &LogDestination, fallback_log_dir: &Path, threshold_ms: u64, sample_pct: u8, ) -> Arc<Self>

Resolve a crate::storage::layout::LogDestination into a concrete slow-query sink. File(p) writes to that exact path; Stderr and Syslog fall back to <fallback_log_dir>/red-slow.log until the dedicated sinks are wired (ADR 0018).

pub fn attach_store(&self, store: Arc<SlowQueryStore>)

Attach the operational telemetry substrate store (ADR 0060).

Called once at runtime startup. Above-threshold, sampled events will be written to both the file sink and the ring store. A second call is a no-op (first registration wins).

pub fn record( &self, kind: QueryKind, duration_ms: u64, sql_redacted: String, scope: &EffectiveScope, )

Record a completed query. Below-threshold: single relaxed load, no allocation. Above-threshold + sampled: emit a JSON line to the sink.
