The death-spiral amplifier: pruneStatusLog ran a whole-table ROW_NUMBER() sort, 40-48s synchronous on the 1.1M-row incident table, freezing boot -> healthcheck fail -> restart loop. - lib/chunked-prune.js: shared chunkedDelete (rowid IN (SELECT ... LIMIT ?) since better-sqlite3 has no DELETE...LIMIT) — bounded batch + setImmediate yield between batches, optional band-gate. Core invariant: no sync op blocks >~50ms ever. - pruneStatusLog: rewritten per-device via a loose index-scan seek (WHERE device_id > ? ORDER BY device_id LIMIT 1 — O(log n) each), retention + newest-cap trimmed in bounded batches, async, re-entrancy-guarded, band-gated on the interval / un-gated + fire-and-forget at startup so a bloated table self-heals on deploy WITHOUT freezing boot. - heartbeat.js: maintenance moved off the interval body into async band-gated re-entrant runMaintenance(); play_logs + provisioning prunes chunked; offline-marking stays synchronous. - pruneTelemetry: bounded single statement (OFFSET 6000 LIMIT batch), stays sync. - idx_devices_provisioning so the provisioning prune batch subquery is an index range. Tests: correctness (per-device cap + retention, independent devices), 300k-row backlog trims in many batches with max event-loop gap <250ms, band-gate no-op while critical + startup runs regardless, re-entrancy (concurrent -> once). Existing prune tests updated to await. Suite 247/247. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
